Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604112, here are decompositions:

13 + 31604099 = 31604112
61 + 31604051 = 31604112
79 + 31604033 = 31604112
179 + 31603933 = 31604112
181 + 31603931 = 31604112
193 + 31603919 = 31604112
223 + 31603889 = 31604112
233 + 31603879 = 31604112

Showing the first eight; more decompositions exist.
