Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609448, here are decompositions:

67 + 31609381 = 31609448
109 + 31609339 = 31609448
181 + 31609267 = 31609448
331 + 31609117 = 31609448
337 + 31609111 = 31609448
631 + 31608817 = 31609448
691 + 31608757 = 31609448
727 + 31608721 = 31609448

Showing the first eight; more decompositions exist.
