Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616198, here are decompositions:

139 + 31616059 = 31616198
151 + 31616047 = 31616198
157 + 31616041 = 31616198
181 + 31616017 = 31616198
199 + 31615999 = 31616198
277 + 31615921 = 31616198
307 + 31615891 = 31616198
349 + 31615849 = 31616198

Showing the first eight; more decompositions exist.
