Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604534, here are decompositions:

37 + 31604497 = 31604534
151 + 31604383 = 31604534
163 + 31604371 = 31604534
193 + 31604341 = 31604534
223 + 31604311 = 31604534
271 + 31604263 = 31604534
307 + 31604227 = 31604534
397 + 31604137 = 31604534

Showing the first eight; more decompositions exist.
