Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617102, here are decompositions:

29 + 31617073 = 31617102
53 + 31617049 = 31617102
73 + 31617029 = 31617102
79 + 31617023 = 31617102
89 + 31617013 = 31617102
103 + 31616999 = 31617102
151 + 31616951 = 31617102
173 + 31616929 = 31617102

Showing the first eight; more decompositions exist.
