Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689740, here are decompositions:

11 + 8689729 = 8689740
13 + 8689727 = 8689740
29 + 8689711 = 8689740
53 + 8689687 = 8689740
67 + 8689673 = 8689740
79 + 8689661 = 8689740
83 + 8689657 = 8689740
97 + 8689643 = 8689740

Showing the first eight; more decompositions exist.
