Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516746, here are decompositions:

17 + 31516729 = 31516746
43 + 31516703 = 31516746
47 + 31516699 = 31516746
113 + 31516633 = 31516746
127 + 31516619 = 31516746
179 + 31516567 = 31516746
223 + 31516523 = 31516746
227 + 31516519 = 31516746

Showing the first eight; more decompositions exist.
