Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604526, here are decompositions:

17 + 31604509 = 31604526
29 + 31604497 = 31604526
73 + 31604453 = 31604526
139 + 31604387 = 31604526
167 + 31604359 = 31604526
179 + 31604347 = 31604526
223 + 31604303 = 31604526
227 + 31604299 = 31604526

Showing the first eight; more decompositions exist.
