Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617016, here are decompositions:

3 + 31617013 = 31617016
5 + 31617011 = 31617016
17 + 31616999 = 31617016
29 + 31616987 = 31617016
83 + 31616933 = 31617016
113 + 31616903 = 31617016
269 + 31616747 = 31617016
593 + 31616423 = 31617016

Showing the first eight; more decompositions exist.
