Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604946, here are decompositions:

13 + 31604933 = 31604946
83 + 31604863 = 31604946
97 + 31604849 = 31604946
157 + 31604789 = 31604946
179 + 31604767 = 31604946
199 + 31604747 = 31604946
223 + 31604723 = 31604946
227 + 31604719 = 31604946

Showing the first eight; more decompositions exist.
