Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514618, here are decompositions:

19 + 31514599 = 31514618
67 + 31514551 = 31514618
139 + 31514479 = 31514618
199 + 31514419 = 31514618
379 + 31514239 = 31514618
397 + 31514221 = 31514618
631 + 31513987 = 31514618
661 + 31513957 = 31514618

Showing the first eight; more decompositions exist.
