Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041728, here are decompositions:

109 + 1041619 = 1041728
151 + 1041577 = 1041728
157 + 1041571 = 1041728
199 + 1041529 = 1041728
211 + 1041517 = 1041728
277 + 1041451 = 1041728
307 + 1041421 = 1041728
379 + 1041349 = 1041728

Showing the first eight; more decompositions exist.
