Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604118, here are decompositions:

19 + 31604099 = 31604118
61 + 31604057 = 31604118
67 + 31604051 = 31604118
127 + 31603991 = 31604118
131 + 31603987 = 31604118
199 + 31603919 = 31604118
229 + 31603889 = 31604118
239 + 31603879 = 31604118

Showing the first eight; more decompositions exist.
