Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604376, here are decompositions:

5 + 31604371 = 31604376
17 + 31604359 = 31604376
19 + 31604357 = 31604376
29 + 31604347 = 31604376
73 + 31604303 = 31604376
79 + 31604297 = 31604376
113 + 31604263 = 31604376
149 + 31604227 = 31604376

Showing the first eight; more decompositions exist.
