Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514456, here are decompositions:

7 + 31514449 = 31514456
37 + 31514419 = 31514456
307 + 31514149 = 31514456
313 + 31514143 = 31514456
397 + 31514059 = 31514456
433 + 31514023 = 31514456
499 + 31513957 = 31514456
577 + 31513879 = 31514456

Showing the first eight; more decompositions exist.
