%N Primes p which can be written in the form 2^i + q^j where i >= 0, j >= 1, q = odd prime.

%C a(n)=A000040(n) for n<=34, but A000040(35)=149 is a term of A115231;

%C A115233 is a subsequence; the union with A115231 gives all primes (A000040);

%C A006512 and A053703 are subsequences.

%Y Cf. A000079, A061345.
