Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604846, here are decompositions:

43 + 31604803 = 31604846
79 + 31604767 = 31604846
103 + 31604743 = 31604846
127 + 31604719 = 31604846
157 + 31604689 = 31604846
199 + 31604647 = 31604846
313 + 31604533 = 31604846
337 + 31604509 = 31604846

Showing the first eight; more decompositions exist.
