Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688730, here are decompositions:

23 + 8688707 = 8688730
59 + 8688671 = 8688730
101 + 8688629 = 8688730
137 + 8688593 = 8688730
173 + 8688557 = 8688730
179 + 8688551 = 8688730
233 + 8688497 = 8688730
293 + 8688437 = 8688730

Showing the first eight; more decompositions exist.
