Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604392, here are decompositions:

5 + 31604387 = 31604392
89 + 31604303 = 31604392
173 + 31604219 = 31604392
263 + 31604129 = 31604392
293 + 31604099 = 31604392
359 + 31604033 = 31604392
401 + 31603991 = 31604392
461 + 31603931 = 31604392

Showing the first eight; more decompositions exist.
