Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626866, here are decompositions:

5 + 8626861 = 8626866
19 + 8626847 = 8626866
43 + 8626823 = 8626866
47 + 8626819 = 8626866
89 + 8626777 = 8626866
103 + 8626763 = 8626866
167 + 8626699 = 8626866
197 + 8626669 = 8626866

Showing the first eight; more decompositions exist.
