Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012728, here are decompositions:

7 + 1012721 = 1012728
11 + 1012717 = 1012728
29 + 1012699 = 1012728
37 + 1012691 = 1012728
71 + 1012657 = 1012728
97 + 1012631 = 1012728
109 + 1012619 = 1012728
127 + 1012601 = 1012728

Showing the first eight; more decompositions exist.
