Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012786, here are decompositions:

17 + 1012769 = 1012786
23 + 1012763 = 1012786
53 + 1012733 = 1012786
83 + 1012703 = 1012786
107 + 1012679 = 1012786
149 + 1012637 = 1012786
167 + 1012619 = 1012786
227 + 1012559 = 1012786

Showing the first eight; more decompositions exist.
