Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040806, here are decompositions:

3 + 1040803 = 1040806
23 + 1040783 = 1040806
29 + 1040777 = 1040806
59 + 1040747 = 1040806
89 + 1040717 = 1040806
149 + 1040657 = 1040806
227 + 1040579 = 1040806
317 + 1040489 = 1040806

Showing the first eight; more decompositions exist.
