Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616086, here are decompositions:

17 + 31616069 = 31616086
53 + 31616033 = 31616086
107 + 31615979 = 31616086
113 + 31615973 = 31616086
167 + 31615919 = 31616086
239 + 31615847 = 31616086
503 + 31615583 = 31616086
647 + 31615439 = 31616086

Showing the first eight; more decompositions exist.
