Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516414, here are decompositions:

3 + 31516411 = 31516414
53 + 31516361 = 31516414
173 + 31516241 = 31516414
257 + 31516157 = 31516414
311 + 31516103 = 31516414
353 + 31516061 = 31516414
521 + 31515893 = 31516414
557 + 31515857 = 31516414

Showing the first eight; more decompositions exist.
