Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616470, here are decompositions:

47 + 31616423 = 31616470
59 + 31616411 = 31616470
89 + 31616381 = 31616470
101 + 31616369 = 31616470
107 + 31616363 = 31616470
131 + 31616339 = 31616470
173 + 31616297 = 31616470
239 + 31616231 = 31616470

Showing the first eight; more decompositions exist.
