Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604604, here are decompositions:

43 + 31604561 = 31604604
47 + 31604557 = 31604604
71 + 31604533 = 31604604
103 + 31604501 = 31604604
107 + 31604497 = 31604604
151 + 31604453 = 31604604
233 + 31604371 = 31604604
257 + 31604347 = 31604604

Showing the first eight; more decompositions exist.
