It is conjectured that this sequence is finite and all terms are found.
EXAMPLE
MATHEMATICA
p = 3; sp = {p}; m = 0; Table[While[m++; l = Length[sp]; While[sp[[l]] < m, While[p = NextPrime[p]; cp = 2*3^(Floor[Log[3, 2*p - 1]]) - p; ! PrimeQ[cp]]; AppendTo[sp, p]; l++]; c = 2 - Mod[m + 1, 2]; ct = 0; Do[If[MemberQ[sp, m - c*sp[[i]]], If[c == 1, If[(2*sp[[i]]) <= m, ct++], ct++]], {i, 1, l}]; ct != 0]; m, {n, 1, 25}]
