Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616116, here are decompositions:

3 + 31616113 = 31616116
47 + 31616069 = 31616116
83 + 31616033 = 31616116
107 + 31616009 = 31616116
137 + 31615979 = 31616116
197 + 31615919 = 31616116
269 + 31615847 = 31616116
353 + 31615763 = 31616116

Showing the first eight; more decompositions exist.
