Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604298, here are decompositions:

17 + 31604281 = 31604298
71 + 31604227 = 31604298
79 + 31604219 = 31604298
107 + 31604191 = 31604298
109 + 31604189 = 31604298
199 + 31604099 = 31604298
241 + 31604057 = 31604298
307 + 31603991 = 31604298

Showing the first eight; more decompositions exist.
