Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700556, here are decompositions:

17 + 8700539 = 8700556
83 + 8700473 = 8700556
89 + 8700467 = 8700556
107 + 8700449 = 8700556
149 + 8700407 = 8700556
173 + 8700383 = 8700556
257 + 8700299 = 8700556
269 + 8700287 = 8700556

Showing the first eight; more decompositions exist.
