Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604612, here are decompositions:

3 + 31604609 = 31604612
79 + 31604533 = 31604612
103 + 31604509 = 31604612
229 + 31604383 = 31604612
241 + 31604371 = 31604612
271 + 31604341 = 31604612
313 + 31604299 = 31604612
331 + 31604281 = 31604612

Showing the first eight; more decompositions exist.
