Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604402, here are decompositions:

19 + 31604383 = 31604402
31 + 31604371 = 31604402
43 + 31604359 = 31604402
61 + 31604341 = 31604402
103 + 31604299 = 31604402
139 + 31604263 = 31604402
211 + 31604191 = 31604402
523 + 31603879 = 31604402

Showing the first eight; more decompositions exist.
