Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604508, here are decompositions:

7 + 31604501 = 31604508
11 + 31604497 = 31604508
137 + 31604371 = 31604508
149 + 31604359 = 31604508
151 + 31604357 = 31604508
167 + 31604341 = 31604508
197 + 31604311 = 31604508
211 + 31604297 = 31604508

Showing the first eight; more decompositions exist.
