Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604966, here are decompositions:

7 + 31604959 = 31604966
103 + 31604863 = 31604966
163 + 31604803 = 31604966
199 + 31604767 = 31604966
223 + 31604743 = 31604966
277 + 31604689 = 31604966
409 + 31604557 = 31604966
433 + 31604533 = 31604966

Showing the first eight; more decompositions exist.
