Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604458, here are decompositions:

5 + 31604453 = 31604458
71 + 31604387 = 31604458
101 + 31604357 = 31604458
239 + 31604219 = 31604458
269 + 31604189 = 31604458
359 + 31604099 = 31604458
401 + 31604057 = 31604458
467 + 31603991 = 31604458

Showing the first eight; more decompositions exist.
