Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514466, here are decompositions:

17 + 31514449 = 31514466
37 + 31514429 = 31514466
43 + 31514423 = 31514466
47 + 31514419 = 31514466
157 + 31514309 = 31514466
199 + 31514267 = 31514466
227 + 31514239 = 31514466
307 + 31514159 = 31514466

Showing the first eight; more decompositions exist.
