%C A007528 Contribution from Cino Hilliard (hillcino368(AT)hotmail.com), Nov 12 
               2008: (Start)
%C A007528 Also primes p such that p^q - 2 is not prime where q is an odd prime. 
               These
%C A007528 numbers cannot be prime because the binomial p^q = (6n-1)^q expands to 
               6h-1
%C A007528 some h. Then p^q-2 = 6h-1-2 is divisible by 3 thus not prime. (End)
