Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514656, here are decompositions:

3 + 31514653 = 31514656
29 + 31514627 = 31514656
83 + 31514573 = 31514656
179 + 31514477 = 31514656
227 + 31514429 = 31514656
233 + 31514423 = 31514656
347 + 31514309 = 31514656
359 + 31514297 = 31514656

Showing the first eight; more decompositions exist.
