Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604550, here are decompositions:

17 + 31604533 = 31604550
41 + 31604509 = 31604550
53 + 31604497 = 31604550
97 + 31604453 = 31604550
163 + 31604387 = 31604550
167 + 31604383 = 31604550
179 + 31604371 = 31604550
191 + 31604359 = 31604550

Showing the first eight; more decompositions exist.
