Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604522, here are decompositions:

13 + 31604509 = 31604522
139 + 31604383 = 31604522
151 + 31604371 = 31604522
163 + 31604359 = 31604522
181 + 31604341 = 31604522
211 + 31604311 = 31604522
223 + 31604299 = 31604522
241 + 31604281 = 31604522

Showing the first eight; more decompositions exist.
