Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040730, here are decompositions:

13 + 1040717 = 1040730
59 + 1040671 = 1040730
71 + 1040659 = 1040730
73 + 1040657 = 1040730
79 + 1040651 = 1040730
101 + 1040629 = 1040730
149 + 1040581 = 1040730
151 + 1040579 = 1040730

Showing the first eight; more decompositions exist.
