Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617012, here are decompositions:

13 + 31616999 = 31617012
61 + 31616951 = 31617012
79 + 31616933 = 31617012
83 + 31616929 = 31617012
109 + 31616903 = 31617012
173 + 31616839 = 31617012
239 + 31616773 = 31617012
263 + 31616749 = 31617012

Showing the first eight; more decompositions exist.
