%S 1,3,5,59,151
%N Odd numbers, x, such that for all primes (p,q) such that x = p + 2q, x + 2p and x + 2q are composite.
%C The sequence is conjectured to be finite and full in A046927. The conjecture holds through 10^9.
%e For 59, (p,q) can be (13,23), (37,11), and (53,3). 59 + 2 * 13, 59 + 2 * 23, ... 59 + 2 * 3 are all composite, so 59 is in the sequence.
%Y Cf. A046927.
