Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639836, here are decompositions:

17 + 8639819 = 8639836
83 + 8639753 = 8639836
89 + 8639747 = 8639836
173 + 8639663 = 8639836
197 + 8639639 = 8639836
239 + 8639597 = 8639836
269 + 8639567 = 8639836
383 + 8639453 = 8639836

Showing the first eight; more decompositions exist.
