Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516104, here are decompositions:

5 + 31516099 = 31516104
17 + 31516087 = 31516104
23 + 31516081 = 31516104
43 + 31516061 = 31516104
83 + 31516021 = 31516104
97 + 31516007 = 31516104
163 + 31515941 = 31516104
167 + 31515937 = 31516104

Showing the first eight; more decompositions exist.
