Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604362, here are decompositions:

3 + 31604359 = 31604362
5 + 31604357 = 31604362
59 + 31604303 = 31604362
173 + 31604189 = 31604362
233 + 31604129 = 31604362
263 + 31604099 = 31604362
311 + 31604051 = 31604362
431 + 31603931 = 31604362

Showing the first eight; more decompositions exist.
