Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604410, here are decompositions:

23 + 31604387 = 31604410
53 + 31604357 = 31604410
107 + 31604303 = 31604410
113 + 31604297 = 31604410
191 + 31604219 = 31604410
281 + 31604129 = 31604410
311 + 31604099 = 31604410
353 + 31604057 = 31604410

Showing the first eight; more decompositions exist.
