Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604360, here are decompositions:

3 + 31604357 = 31604360
13 + 31604347 = 31604360
19 + 31604341 = 31604360
61 + 31604299 = 31604360
79 + 31604281 = 31604360
97 + 31604263 = 31604360
223 + 31604137 = 31604360
373 + 31603987 = 31604360

Showing the first eight; more decompositions exist.
