Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516044, here are decompositions:

17 + 31516027 = 31516044
23 + 31516021 = 31516044
37 + 31516007 = 31516044
103 + 31515941 = 31516044
107 + 31515937 = 31516044
113 + 31515931 = 31516044
151 + 31515893 = 31516044
163 + 31515881 = 31516044

Showing the first eight; more decompositions exist.
