%N A179612 Sums of pairs of betrothed (or quasi-amicable) numbers.
%C A179612 This is to A161005 sums of pairs of amicable numbers as betrothed (or quasi-amicable) numbers A005276 are to A063990 amicable numbers. The subsequence of primes begins: 11903, 138239, 1071359.
%F A179612 a(n) = A003502(n) + A003503(n). {(j + k) such that sigma(j)=sigma(k)=j+k+1, where sigma=A000203}.
%e A179612 a(1) = 48 + 75 = 123 = 3 * 41.
%e A179612 a(2) = 140 + 195 = 335 = 5 * 67.
%e A179612 a(6) = 5775 + 6128 = 11903 is the smallest prime in these pair-sums.
%Y A179612 Cf. A000203, A003502, A003503, A005276, A063990, A161005.
