is every prime p equals another prime p' plus or minus a power of 2? p=p'+/-2^n? are there infinitely many primes not of this form?

To make your questions better, you might want to include some background or motivation. Why are you interested? What have you tried already? etc. – Gjergji Zaimi Dec 18 '10 at 10:43
one can look at mathoverflow.net/questions/49751/… – asterios gantzounis Dec 18 '10 at 10:47

is this allowed? – asterios gantzounis Dec 18 '10 at 11:02
It's very much discouraged since it makes the thread look like nonsense. Changing your question to make an existing answer a non-answer is something like inviting to treat somebody to dinner, then slipping out after the meal, sticking them with the bill. – Anton Geraschenko Dec 22 '10 at 18:01
