Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040816, here are decompositions:

3 + 1040813 = 1040816
13 + 1040803 = 1040816
19 + 1040797 = 1040816
37 + 1040779 = 1040816
67 + 1040749 = 1040816
157 + 1040659 = 1040816
313 + 1040503 = 1040816
367 + 1040449 = 1040816

Showing the first eight; more decompositions exist.
