Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688550, here are decompositions:

23 + 8688527 = 8688550
29 + 8688521 = 8688550
53 + 8688497 = 8688550
113 + 8688437 = 8688550
197 + 8688353 = 8688550
239 + 8688311 = 8688550
251 + 8688299 = 8688550
263 + 8688287 = 8688550

Showing the first eight; more decompositions exist.
