Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516088, here are decompositions:

7 + 31516081 = 31516088
61 + 31516027 = 31516088
67 + 31516021 = 31516088
139 + 31515949 = 31516088
151 + 31515937 = 31516088
157 + 31515931 = 31516088
787 + 31515301 = 31516088
1009 + 31515079 = 31516088

Showing the first eight; more decompositions exist.
