Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604790, here are decompositions:

23 + 31604767 = 31604790
31 + 31604759 = 31604790
43 + 31604747 = 31604790
47 + 31604743 = 31604790
59 + 31604731 = 31604790
67 + 31604723 = 31604790
71 + 31604719 = 31604790
101 + 31604689 = 31604790

Showing the first eight; more decompositions exist.
