Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616048, here are decompositions:

7 + 31616041 = 31616048
31 + 31616017 = 31616048
97 + 31615951 = 31616048
127 + 31615921 = 31616048
157 + 31615891 = 31616048
199 + 31615849 = 31616048
241 + 31615807 = 31616048
307 + 31615741 = 31616048

Showing the first eight; more decompositions exist.
