Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614518, here are decompositions:

241 + 31614277 = 31614518
307 + 31614211 = 31614518
337 + 31614181 = 31614518
409 + 31614109 = 31614518
421 + 31614097 = 31614518
457 + 31614061 = 31614518
499 + 31614019 = 31614518
937 + 31613581 = 31614518

Showing the first eight; more decompositions exist.
