Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040784, here are decompositions:

5 + 1040779 = 1040784
7 + 1040777 = 1040784
13 + 1040771 = 1040784
37 + 1040747 = 1040784
53 + 1040731 = 1040784
67 + 1040717 = 1040784
113 + 1040671 = 1040784
127 + 1040657 = 1040784

Showing the first eight; more decompositions exist.
