Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617056, here are decompositions:

7 + 31617049 = 31617056
43 + 31617013 = 31617056
127 + 31616929 = 31617056
139 + 31616917 = 31617056
199 + 31616857 = 31617056
283 + 31616773 = 31617056
307 + 31616749 = 31617056
349 + 31616707 = 31617056

Showing the first eight; more decompositions exist.
