Related to Martin Gardner's "Impossible Problem".
a(n) is thus a subsequence of A086473, itself a subsequence of A058080. Consider the mapping f:P>S defined thus: S is the sum of a factor pair (both different from 1) of P, where P is a(n). If S is A086533(n) (a subsequence of A014092), then both f and its inverse are injective (but not onto).
