Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604274, here are decompositions:

11 + 31604263 = 31604274
47 + 31604227 = 31604274
83 + 31604191 = 31604274
137 + 31604137 = 31604274
223 + 31604051 = 31604274
241 + 31604033 = 31604274
283 + 31603991 = 31604274
397 + 31603877 = 31604274

Showing the first eight; more decompositions exist.
