Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616634, here are decompositions:

11 + 31616623 = 31616634
31 + 31616603 = 31616634
73 + 31616561 = 31616634
113 + 31616521 = 31616634
211 + 31616423 = 31616634
223 + 31616411 = 31616634
233 + 31616401 = 31616634
241 + 31616393 = 31616634

Showing the first eight; more decompositions exist.
