Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574508, here are decompositions:

11 + 31574497 = 31574508
19 + 31574489 = 31574508
29 + 31574479 = 31574508
41 + 31574467 = 31574508
59 + 31574449 = 31574508
71 + 31574437 = 31574508
79 + 31574429 = 31574508
89 + 31574419 = 31574508

Showing the first eight; more decompositions exist.
