Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617010, here are decompositions:

11 + 31616999 = 31617010
23 + 31616987 = 31617010
59 + 31616951 = 31617010
107 + 31616903 = 31617010
263 + 31616747 = 31617010
281 + 31616729 = 31617010
317 + 31616693 = 31617010
431 + 31616579 = 31617010

Showing the first eight; more decompositions exist.
