Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1061640, here are decompositions:

11 + 1061629 = 1061640
17 + 1061623 = 1061640
23 + 1061617 = 1061640
31 + 1061609 = 1061640
43 + 1061597 = 1061640
67 + 1061573 = 1061640
71 + 1061569 = 1061640
79 + 1061561 = 1061640

Showing the first eight; more decompositions exist.
