Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604504, here are decompositions:

3 + 31604501 = 31604504
7 + 31604497 = 31604504
157 + 31604347 = 31604504
163 + 31604341 = 31604504
193 + 31604311 = 31604504
223 + 31604281 = 31604504
241 + 31604263 = 31604504
277 + 31604227 = 31604504

Showing the first eight; more decompositions exist.
