Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574520, here are decompositions:

13 + 31574507 = 31574520
23 + 31574497 = 31574520
31 + 31574489 = 31574520
41 + 31574479 = 31574520
53 + 31574467 = 31574520
67 + 31574453 = 31574520
71 + 31574449 = 31574520
83 + 31574437 = 31574520

Showing the first eight; more decompositions exist.
