Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616464, here are decompositions:

41 + 31616423 = 31616464
53 + 31616411 = 31616464
71 + 31616393 = 31616464
83 + 31616381 = 31616464
101 + 31616363 = 31616464
137 + 31616327 = 31616464
167 + 31616297 = 31616464
233 + 31616231 = 31616464

Showing the first eight; more decompositions exist.
