Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516038, here are decompositions:

11 + 31516027 = 31516038
17 + 31516021 = 31516038
31 + 31516007 = 31516038
89 + 31515949 = 31516038
97 + 31515941 = 31516038
101 + 31515937 = 31516038
107 + 31515931 = 31516038
139 + 31515899 = 31516038

Showing the first eight; more decompositions exist.
