Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040646, here are decompositions:

17 + 1040629 = 1040646
67 + 1040579 = 1040646
83 + 1040563 = 1040646
157 + 1040489 = 1040646
163 + 1040483 = 1040646
197 + 1040449 = 1040646
199 + 1040447 = 1040646
227 + 1040419 = 1040646

Showing the first eight; more decompositions exist.
