Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604384, here are decompositions:

13 + 31604371 = 31604384
37 + 31604347 = 31604384
43 + 31604341 = 31604384
73 + 31604311 = 31604384
103 + 31604281 = 31604384
157 + 31604227 = 31604384
193 + 31604191 = 31604384
397 + 31603987 = 31604384

Showing the first eight; more decompositions exist.
