Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604340, here are decompositions:

29 + 31604311 = 31604340
37 + 31604303 = 31604340
41 + 31604299 = 31604340
43 + 31604297 = 31604340
59 + 31604281 = 31604340
113 + 31604227 = 31604340
149 + 31604191 = 31604340
151 + 31604189 = 31604340

Showing the first eight; more decompositions exist.
