Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604510, here are decompositions:

13 + 31604497 = 31604510
127 + 31604383 = 31604510
139 + 31604371 = 31604510
151 + 31604359 = 31604510
163 + 31604347 = 31604510
199 + 31604311 = 31604510
211 + 31604299 = 31604510
229 + 31604281 = 31604510

Showing the first eight; more decompositions exist.
