Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516162, here are decompositions:

3 + 31516159 = 31516162
5 + 31516157 = 31516162
23 + 31516139 = 31516162
53 + 31516109 = 31516162
59 + 31516103 = 31516162
101 + 31516061 = 31516162
173 + 31515989 = 31516162
263 + 31515899 = 31516162

Showing the first eight; more decompositions exist.
