Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688636, here are decompositions:

7 + 8688629 = 8688636
23 + 8688613 = 8688636
29 + 8688607 = 8688636
43 + 8688593 = 8688636
53 + 8688583 = 8688636
59 + 8688577 = 8688636
67 + 8688569 = 8688636
79 + 8688557 = 8688636

Showing the first eight; more decompositions exist.
