Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516006, here are decompositions:

17 + 31515989 = 31516006
107 + 31515899 = 31516006
113 + 31515893 = 31516006
149 + 31515857 = 31516006
239 + 31515767 = 31516006
359 + 31515647 = 31516006
443 + 31515563 = 31516006
449 + 31515557 = 31516006

Showing the first eight; more decompositions exist.
