Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688660, here are decompositions:

31 + 8688629 = 8688660
47 + 8688613 = 8688660
53 + 8688607 = 8688660
59 + 8688601 = 8688660
67 + 8688593 = 8688660
83 + 8688577 = 8688660
89 + 8688571 = 8688660
103 + 8688557 = 8688660

Showing the first eight; more decompositions exist.
