Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700028, here are decompositions:

17 + 8700011 = 8700028
47 + 8699981 = 8700028
59 + 8699969 = 8700028
149 + 8699879 = 8700028
257 + 8699771 = 8700028
461 + 8699567 = 8700028
509 + 8699519 = 8700028
641 + 8699387 = 8700028

Showing the first eight; more decompositions exist.
