Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616646, here are decompositions:

23 + 31616623 = 31616646
43 + 31616603 = 31616646
67 + 31616579 = 31616646
107 + 31616539 = 31616646
137 + 31616509 = 31616646
167 + 31616479 = 31616646
223 + 31616423 = 31616646
227 + 31616419 = 31616646

Showing the first eight; more decompositions exist.
