Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516008, here are decompositions:

19 + 31515989 = 31516008
59 + 31515949 = 31516008
67 + 31515941 = 31516008
71 + 31515937 = 31516008
89 + 31515919 = 31516008
109 + 31515899 = 31516008
127 + 31515881 = 31516008
151 + 31515857 = 31516008

Showing the first eight; more decompositions exist.
