Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516214, here are decompositions:

13 + 31516201 = 31516214
31 + 31516183 = 31516214
61 + 31516153 = 31516214
127 + 31516087 = 31516214
193 + 31516021 = 31516214
277 + 31515937 = 31516214
283 + 31515931 = 31516214
607 + 31515607 = 31516214

Showing the first eight; more decompositions exist.
