Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604406, here are decompositions:

19 + 31604387 = 31604406
23 + 31604383 = 31604406
47 + 31604359 = 31604406
59 + 31604347 = 31604406
103 + 31604303 = 31604406
107 + 31604299 = 31604406
109 + 31604297 = 31604406
179 + 31604227 = 31604406

Showing the first eight; more decompositions exist.
