Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616506, here are decompositions:

83 + 31616423 = 31616506
113 + 31616393 = 31616506
137 + 31616369 = 31616506
167 + 31616339 = 31616506
179 + 31616327 = 31616506
587 + 31615919 = 31616506
659 + 31615847 = 31616506
743 + 31615763 = 31616506

Showing the first eight; more decompositions exist.
