Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040724, here are decompositions:

7 + 1040717 = 1040724
53 + 1040671 = 1040724
67 + 1040657 = 1040724
73 + 1040651 = 1040724
127 + 1040597 = 1040724
193 + 1040531 = 1040724
241 + 1040483 = 1040724
277 + 1040447 = 1040724

Showing the first eight; more decompositions exist.
