Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726866, here are decompositions:

3 + 8726863 = 8726866
17 + 8726849 = 8726866
89 + 8726777 = 8726866
107 + 8726759 = 8726866
167 + 8726699 = 8726866
179 + 8726687 = 8726866
233 + 8726633 = 8726866
293 + 8726573 = 8726866

Showing the first eight; more decompositions exist.
