Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514508, here are decompositions:

29 + 31514479 = 31514508
31 + 31514477 = 31514508
59 + 31514449 = 31514508
79 + 31514429 = 31514508
89 + 31514419 = 31514508
107 + 31514401 = 31514508
199 + 31514309 = 31514508
211 + 31514297 = 31514508

Showing the first eight; more decompositions exist.
