Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614680, here are decompositions:

3 + 31614677 = 31614680
37 + 31614643 = 31614680
79 + 31614601 = 31614680
157 + 31614523 = 31614680
337 + 31614343 = 31614680
397 + 31614283 = 31614680
463 + 31614217 = 31614680
499 + 31614181 = 31614680

Showing the first eight; more decompositions exist.
