Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8696640, here are decompositions:

11 + 8696629 = 8696640
13 + 8696627 = 8696640
23 + 8696617 = 8696640
31 + 8696609 = 8696640
37 + 8696603 = 8696640
59 + 8696581 = 8696640
67 + 8696573 = 8696640
79 + 8696561 = 8696640

Showing the first eight; more decompositions exist.
