Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514514, here are decompositions:

37 + 31514477 = 31514514
41 + 31514473 = 31514514
113 + 31514401 = 31514514
223 + 31514291 = 31514514
293 + 31514221 = 31514514
401 + 31514113 = 31514514
433 + 31514081 = 31514514
491 + 31514023 = 31514514

Showing the first eight; more decompositions exist.
