Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604524, here are decompositions:

23 + 31604501 = 31604524
71 + 31604453 = 31604524
137 + 31604387 = 31604524
167 + 31604357 = 31604524
227 + 31604297 = 31604524
467 + 31604057 = 31604524
491 + 31604033 = 31604524
593 + 31603931 = 31604524

Showing the first eight; more decompositions exist.
