Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617914, here are decompositions:

37 + 31617877 = 31617914
43 + 31617871 = 31617914
61 + 31617853 = 31617914
103 + 31617811 = 31617914
151 + 31617763 = 31617914
157 + 31617757 = 31617914
241 + 31617673 = 31617914
283 + 31617631 = 31617914

Showing the first eight; more decompositions exist.
