Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042728, here are decompositions:

19 + 1042709 = 1042728
41 + 1042687 = 1042728
47 + 1042681 = 1042728
97 + 1042631 = 1042728
109 + 1042619 = 1042728
131 + 1042597 = 1042728
151 + 1042577 = 1042728
157 + 1042571 = 1042728

Showing the first eight; more decompositions exist.
