Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705800, here are decompositions:

23 + 8705777 = 8705800
41 + 8705759 = 8705800
53 + 8705747 = 8705800
71 + 8705729 = 8705800
227 + 8705573 = 8705800
239 + 8705561 = 8705800
251 + 8705549 = 8705800
269 + 8705531 = 8705800

Showing the first eight; more decompositions exist.
