Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516116, here are decompositions:

7 + 31516109 = 31516116
13 + 31516103 = 31516116
17 + 31516099 = 31516116
29 + 31516087 = 31516116
89 + 31516027 = 31516116
109 + 31516007 = 31516116
127 + 31515989 = 31516116
167 + 31515949 = 31516116

Showing the first eight; more decompositions exist.
