Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510674, here are decompositions:

17 + 31510657 = 31510674
43 + 31510631 = 31510674
47 + 31510627 = 31510674
71 + 31510603 = 31510674
101 + 31510573 = 31510674
113 + 31510561 = 31510674
157 + 31510517 = 31510674
227 + 31510447 = 31510674

Showing the first eight; more decompositions exist.
