Nov 21, 2009 at 20:05	comment	added	Jernej		I am not sure why is your argument correct. Can you find a representation for say 37? The only representation I find is 37 = 1*18 + 18 + 1

Nov 21, 2009 at 18:47	comment	added	Charles Siegel		The argument is just to choose an $a$ and a $b$, in particular, $1$ and $2$, and then the problem reduces to "Which primes can be written as $2n+3$ for some $n\geq 2$. That's the same as $(2n+2)+1=2k+1$ for $k\geq 3$, so every odd number greater than seven, and in particular, every odd prime, can be written this way.
