Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688634, here are decompositions:

5 + 8688629 = 8688634
23 + 8688611 = 8688634
41 + 8688593 = 8688634
83 + 8688551 = 8688634
107 + 8688527 = 8688634
113 + 8688521 = 8688634
137 + 8688497 = 8688634
197 + 8688437 = 8688634

Showing the first eight; more decompositions exist.
