Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616150, here are decompositions:

37 + 31616113 = 31616150
103 + 31616047 = 31616150
109 + 31616041 = 31616150
127 + 31616023 = 31616150
151 + 31615999 = 31616150
157 + 31615993 = 31616150
199 + 31615951 = 31616150
229 + 31615921 = 31616150

Showing the first eight; more decompositions exist.
