Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040778, here are decompositions:

7 + 1040771 = 1040778
29 + 1040749 = 1040778
31 + 1040747 = 1040778
47 + 1040731 = 1040778
61 + 1040717 = 1040778
107 + 1040671 = 1040778
127 + 1040651 = 1040778
149 + 1040629 = 1040778

Showing the first eight; more decompositions exist.
