Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514486, here are decompositions:

7 + 31514479 = 31514486
13 + 31514473 = 31514486
37 + 31514449 = 31514486
67 + 31514419 = 31514486
337 + 31514149 = 31514486
373 + 31514113 = 31514486
463 + 31514023 = 31514486
499 + 31513987 = 31514486

Showing the first eight; more decompositions exist.
