Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604398, here are decompositions:

11 + 31604387 = 31604398
41 + 31604357 = 31604398
101 + 31604297 = 31604398
179 + 31604219 = 31604398
269 + 31604129 = 31604398
347 + 31604051 = 31604398
467 + 31603931 = 31604398
479 + 31603919 = 31604398

Showing the first eight; more decompositions exist.
