Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604328, here are decompositions:

17 + 31604311 = 31604328
29 + 31604299 = 31604328
31 + 31604297 = 31604328
47 + 31604281 = 31604328
101 + 31604227 = 31604328
109 + 31604219 = 31604328
137 + 31604191 = 31604328
139 + 31604189 = 31604328

Showing the first eight; more decompositions exist.
