Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688748, here are decompositions:

41 + 8688707 = 8688748
137 + 8688611 = 8688748
179 + 8688569 = 8688748
191 + 8688557 = 8688748
197 + 8688551 = 8688748
227 + 8688521 = 8688748
251 + 8688497 = 8688748
311 + 8688437 = 8688748

Showing the first eight; more decompositions exist.
