Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617108, here are decompositions:

7 + 31617101 = 31617108
31 + 31617077 = 31617108
59 + 31617049 = 31617108
79 + 31617029 = 31617108
97 + 31617011 = 31617108
109 + 31616999 = 31617108
157 + 31616951 = 31617108
179 + 31616929 = 31617108

Showing the first eight; more decompositions exist.
