Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617106, here are decompositions:

5 + 31617101 = 31617106
29 + 31617077 = 31617106
83 + 31617023 = 31617106
107 + 31616999 = 31617106
173 + 31616933 = 31617106
359 + 31616747 = 31617106
419 + 31616687 = 31617106
503 + 31616603 = 31617106

Showing the first eight; more decompositions exist.
