Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616576, here are decompositions:

7 + 31616569 = 31616576
37 + 31616539 = 31616576
67 + 31616509 = 31616576
97 + 31616479 = 31616576
157 + 31616419 = 31616576
463 + 31616113 = 31616576
577 + 31615999 = 31616576
727 + 31615849 = 31616576

Showing the first eight; more decompositions exist.
