Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604272, here are decompositions:

53 + 31604219 = 31604272
83 + 31604189 = 31604272
173 + 31604099 = 31604272
239 + 31604033 = 31604272
281 + 31603991 = 31604272
353 + 31603919 = 31604272
383 + 31603889 = 31604272
443 + 31603829 = 31604272

Showing the first eight; more decompositions exist.
