Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688724, here are decompositions:

17 + 8688707 = 8688724
53 + 8688671 = 8688724
113 + 8688611 = 8688724
131 + 8688593 = 8688724
167 + 8688557 = 8688724
173 + 8688551 = 8688724
197 + 8688527 = 8688724
227 + 8688497 = 8688724

Showing the first eight; more decompositions exist.
