Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012782, here are decompositions:

11 + 1012771 = 1012782
13 + 1012769 = 1012782
19 + 1012763 = 1012782
31 + 1012751 = 1012782
61 + 1012721 = 1012782
79 + 1012703 = 1012782
83 + 1012699 = 1012782
103 + 1012679 = 1012782

Showing the first eight; more decompositions exist.
