Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604468, here are decompositions:

97 + 31604371 = 31604468
109 + 31604359 = 31604468
127 + 31604341 = 31604468
157 + 31604311 = 31604468
241 + 31604227 = 31604468
277 + 31604191 = 31604468
331 + 31604137 = 31604468
751 + 31603717 = 31604468

Showing the first eight; more decompositions exist.
