Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732866, here are decompositions:

5 + 8732861 = 8732866
47 + 8732819 = 8732866
59 + 8732807 = 8732866
179 + 8732687 = 8732866
227 + 8732639 = 8732866
239 + 8732627 = 8732866
293 + 8732573 = 8732866
419 + 8732447 = 8732866

Showing the first eight; more decompositions exist.
