<p>For what it's worth, the 12/12/2012 article at <a href="http://bostonglobe.com/news/science/2012/12/11/math-even-mathematicians-don-understand/e41V2lixnAVyB63X4NTPaO/story.html" rel="nofollow">http://bostonglobe.com/news/science/2012/12/11/math-even-mathematicians-don-understand/e41V2lixnAVyB63X4NTPaO/story.html</a> indicates that Pogorzelski believes that he has established a legitimate demonstration of the Goldbach conjecture (which he claims he obtained in the 1990s). The article quotes from his manuscript's preface that his proof was submitted for publication in 2002, and he received no response. </p>
