Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617966, here are decompositions:

5 + 31617961 = 31617966
7 + 31617959 = 31617966
13 + 31617953 = 31617966
67 + 31617899 = 31617966
89 + 31617877 = 31617966
103 + 31617863 = 31617966
113 + 31617853 = 31617966
139 + 31617827 = 31617966

Showing the first eight; more decompositions exist.
