Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614974, here are decompositions:

31 + 31614943 = 31614974
241 + 31614733 = 31614974
271 + 31614703 = 31614974
277 + 31614697 = 31614974
331 + 31614643 = 31614974
373 + 31614601 = 31614974
631 + 31614343 = 31614974
691 + 31614283 = 31614974

Showing the first eight; more decompositions exist.
