Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639800, here are decompositions:

3 + 8639797 = 8639800
47 + 8639753 = 8639800
53 + 8639747 = 8639800
89 + 8639711 = 8639800
137 + 8639663 = 8639800
233 + 8639567 = 8639800
251 + 8639549 = 8639800
269 + 8639531 = 8639800

Showing the first eight; more decompositions exist.
