Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688664, here are decompositions:

53 + 8688611 = 8688664
71 + 8688593 = 8688664
107 + 8688557 = 8688664
113 + 8688551 = 8688664
137 + 8688527 = 8688664
167 + 8688497 = 8688664
227 + 8688437 = 8688664
311 + 8688353 = 8688664

Showing the first eight; more decompositions exist.
