Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516150, here are decompositions:

11 + 31516139 = 31516150
41 + 31516109 = 31516150
47 + 31516103 = 31516150
89 + 31516061 = 31516150
251 + 31515899 = 31516150
257 + 31515893 = 31516150
269 + 31515881 = 31516150
293 + 31515857 = 31516150

Showing the first eight; more decompositions exist.
