Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461586, here are decompositions:

17 + 31461569 = 31461586
29 + 31461557 = 31461586
53 + 31461533 = 31461586
173 + 31461413 = 31461586
293 + 31461293 = 31461586
659 + 31460927 = 31461586
857 + 31460729 = 31461586
929 + 31460657 = 31461586

Showing the first eight; more decompositions exist.
