This question was marked as an exact duplicate of an existing question.

This shows a downside of the unofficial policy of deleting, rather than just closing, unwanted questions. Had the earlier question not been deleted, there's at least a chance that Dennis Farr would have found it and not posted a duplicate. Now, he knows only that the question has been asked before, but, as far as I know, he can't see that previous post or its comments. So let me repeat here, for his benefit, part of one of those comments (which no one explicitly disagreed with): The Goldbach conjecture remains open. – Andreas Blass Aug 20 '12 at 14:22
Andreas- I'm not sure what you mean by "policy of deleted rather than closing unwanted questions." There was a question on this topic that was deleted (by me) for what I and many other people think were very good reasons (discussed in this thread…). As what actually happened shows, having a closed question on the subject that was publicly viewable actually didn't make a lick of difference. – Ben Webster Aug 20 '12 at 17:55
@Ben Webster: I think there is some confusion. I am pretty sure that Andreas Blass's refers to the fact that the question (104906) linked as duplicate in this question was deleted (by users not mods and without discussion, AFAIK) when he made his comment. (Not to the one you deleted.) This created the (unfortunate) situation that there was a link to a duplicate that was not visible to regular users; the question only subsequently got undeleted by a mod, so that now the problem A.B. refers to is already resolved. Howver, you're right that when this qu. was asked the other one was here. – user9072 Aug 20 '12 at 20:13
If ever anyone cares about the precise timeline (in UTC): 13.37 this qu. asked. 13.48 this qu. closed. 14.02 qu. 104906 deleted. 14.22 Andreas Blass comments. 15.28 qu. 104906 undeleted. – user9072 Aug 20 '12 at 20:17
Quid- thanks for the explanation. Andreas- please excuse any perceived ill-temper in my reply above. I misunderstood your meaning. – Ben Webster Aug 20 '12 at 20:22
