Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012806, here are decompositions:

17 + 1012789 = 1012806
37 + 1012769 = 1012806
43 + 1012763 = 1012806
73 + 1012733 = 1012806
89 + 1012717 = 1012806
103 + 1012703 = 1012806
107 + 1012699 = 1012806
127 + 1012679 = 1012806

Showing the first eight; more decompositions exist.
