Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616126, here are decompositions:

13 + 31616113 = 31616126
67 + 31616059 = 31616126
79 + 31616047 = 31616126
103 + 31616023 = 31616126
109 + 31616017 = 31616126
127 + 31615999 = 31616126
277 + 31615849 = 31616126
397 + 31615729 = 31616126

Showing the first eight; more decompositions exist.
