Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616196, here are decompositions:

13 + 31616183 = 31616196
23 + 31616173 = 31616196
47 + 31616149 = 31616196
67 + 31616129 = 31616196
83 + 31616113 = 31616196
127 + 31616069 = 31616196
137 + 31616059 = 31616196
149 + 31616047 = 31616196

Showing the first eight; more decompositions exist.
