Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688666, here are decompositions:

37 + 8688629 = 8688666
53 + 8688613 = 8688666
59 + 8688607 = 8688666
73 + 8688593 = 8688666
83 + 8688583 = 8688666
89 + 8688577 = 8688666
97 + 8688569 = 8688666
109 + 8688557 = 8688666

Showing the first eight; more decompositions exist.
