Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604492, here are decompositions:

109 + 31604383 = 31604492
151 + 31604341 = 31604492
181 + 31604311 = 31604492
193 + 31604299 = 31604492
211 + 31604281 = 31604492
229 + 31604263 = 31604492
613 + 31603879 = 31604492
691 + 31603801 = 31604492

Showing the first eight; more decompositions exist.
