Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609366, here are decompositions:

137 + 31609229 = 31609366
317 + 31609049 = 31609366
449 + 31608917 = 31609366
479 + 31608887 = 31609366
587 + 31608779 = 31609366
617 + 31608749 = 31609366
653 + 31608713 = 31609366
839 + 31608527 = 31609366

Showing the first eight; more decompositions exist.
