Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514678, here are decompositions:

7 + 31514671 = 31514678
37 + 31514641 = 31514678
79 + 31514599 = 31514678
127 + 31514551 = 31514678
199 + 31514479 = 31514678
229 + 31514449 = 31514678
277 + 31514401 = 31514678
439 + 31514239 = 31514678

Showing the first eight; more decompositions exist.
