Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688916, here are decompositions:

53 + 8688863 = 8688916
107 + 8688809 = 8688916
347 + 8688569 = 8688916
359 + 8688557 = 8688916
389 + 8688527 = 8688916
419 + 8688497 = 8688916
479 + 8688437 = 8688916
563 + 8688353 = 8688916

Showing the first eight; more decompositions exist.
