Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043728, here are decompositions:

5 + 1043723 = 1043728
71 + 1043657 = 1043728
89 + 1043639 = 1043728
131 + 1043597 = 1043728
137 + 1043591 = 1043728
197 + 1043531 = 1043728
227 + 1043501 = 1043728
239 + 1043489 = 1043728

Showing the first eight; more decompositions exist.
