Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604316, here are decompositions:

5 + 31604311 = 31604316
13 + 31604303 = 31604316
17 + 31604299 = 31604316
19 + 31604297 = 31604316
53 + 31604263 = 31604316
89 + 31604227 = 31604316
97 + 31604219 = 31604316
127 + 31604189 = 31604316

Showing the first eight; more decompositions exist.
