Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688736, here are decompositions:

29 + 8688707 = 8688736
107 + 8688629 = 8688736
167 + 8688569 = 8688736
179 + 8688557 = 8688736
239 + 8688497 = 8688736
383 + 8688353 = 8688736
449 + 8688287 = 8688736
569 + 8688167 = 8688736

Showing the first eight; more decompositions exist.
