Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688628, here are decompositions:

17 + 8688611 = 8688628
59 + 8688569 = 8688628
71 + 8688557 = 8688628
101 + 8688527 = 8688628
107 + 8688521 = 8688628
131 + 8688497 = 8688628
191 + 8688437 = 8688628
317 + 8688311 = 8688628

Showing the first eight; more decompositions exist.
