Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609508, here are decompositions:

127 + 31609381 = 31609508
241 + 31609267 = 31609508
277 + 31609231 = 31609508
397 + 31609111 = 31609508
421 + 31609087 = 31609508
571 + 31608937 = 31609508
691 + 31608817 = 31609508
751 + 31608757 = 31609508

Showing the first eight; more decompositions exist.
