Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617090, here are decompositions:

13 + 31617077 = 31617090
17 + 31617073 = 31617090
41 + 31617049 = 31617090
61 + 31617029 = 31617090
67 + 31617023 = 31617090
79 + 31617011 = 31617090
103 + 31616987 = 31617090
139 + 31616951 = 31617090

Showing the first eight; more decompositions exist.
