Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700666, here are decompositions:

17 + 8700649 = 8700666
67 + 8700599 = 8700666
103 + 8700563 = 8700666
127 + 8700539 = 8700666
137 + 8700529 = 8700666
193 + 8700473 = 8700666
199 + 8700467 = 8700666
283 + 8700383 = 8700666

Showing the first eight; more decompositions exist.
