Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689724, here are decompositions:

13 + 8689711 = 8689724
37 + 8689687 = 8689724
67 + 8689657 = 8689724
97 + 8689627 = 8689724
151 + 8689573 = 8689724
181 + 8689543 = 8689724
271 + 8689453 = 8689724
613 + 8689111 = 8689724

Showing the first eight; more decompositions exist.
