Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574908, here are decompositions:

17 + 31574891 = 31574908
47 + 31574861 = 31574908
59 + 31574849 = 31574908
227 + 31574681 = 31574908
251 + 31574657 = 31574908
269 + 31574639 = 31574908
401 + 31574507 = 31574908
419 + 31574489 = 31574908

Showing the first eight; more decompositions exist.
