Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688670, here are decompositions:

41 + 8688629 = 8688670
59 + 8688611 = 8688670
101 + 8688569 = 8688670
113 + 8688557 = 8688670
149 + 8688521 = 8688670
173 + 8688497 = 8688670
233 + 8688437 = 8688670
317 + 8688353 = 8688670

Showing the first eight; more decompositions exist.
