Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604364, here are decompositions:

5 + 31604359 = 31604364
7 + 31604357 = 31604364
17 + 31604347 = 31604364
23 + 31604341 = 31604364
53 + 31604311 = 31604364
61 + 31604303 = 31604364
67 + 31604297 = 31604364
83 + 31604281 = 31604364

Showing the first eight; more decompositions exist.
