Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516032, here are decompositions:

5 + 31516027 = 31516032
11 + 31516021 = 31516032
43 + 31515989 = 31516032
83 + 31515949 = 31516032
101 + 31515931 = 31516032
113 + 31515919 = 31516032
139 + 31515893 = 31516032
151 + 31515881 = 31516032

Showing the first eight; more decompositions exist.
