Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040786, here are decompositions:

3 + 1040783 = 1040786
7 + 1040779 = 1040786
37 + 1040749 = 1040786
127 + 1040659 = 1040786
157 + 1040629 = 1040786
223 + 1040563 = 1040786
283 + 1040503 = 1040786
337 + 1040449 = 1040786

Showing the first eight; more decompositions exist.
