Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616850, here are decompositions:

11 + 31616839 = 31616850
101 + 31616749 = 31616850
103 + 31616747 = 31616850
157 + 31616693 = 31616850
163 + 31616687 = 31616850
173 + 31616677 = 31616850
179 + 31616671 = 31616850
227 + 31616623 = 31616850

Showing the first eight; more decompositions exist.
