Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604326, here are decompositions:

23 + 31604303 = 31604326
29 + 31604297 = 31604326
107 + 31604219 = 31604326
137 + 31604189 = 31604326
197 + 31604129 = 31604326
227 + 31604099 = 31604326
269 + 31604057 = 31604326
293 + 31604033 = 31604326

Showing the first eight; more decompositions exist.
