Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716638, here are decompositions:

11 + 8716627 = 8716638
19 + 8716619 = 8716638
59 + 8716579 = 8716638
71 + 8716567 = 8716638
107 + 8716531 = 8716638
149 + 8716489 = 8716638
191 + 8716447 = 8716638
197 + 8716441 = 8716638

Showing the first eight; more decompositions exist.
