Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604386, here are decompositions:

3 + 31604383 = 31604386
29 + 31604357 = 31604386
83 + 31604303 = 31604386
89 + 31604297 = 31604386
167 + 31604219 = 31604386
197 + 31604189 = 31604386
257 + 31604129 = 31604386
353 + 31604033 = 31604386

Showing the first eight; more decompositions exist.
