Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639794, here are decompositions:

41 + 8639753 = 8639794
47 + 8639747 = 8639794
83 + 8639711 = 8639794
131 + 8639663 = 8639794
197 + 8639597 = 8639794
227 + 8639567 = 8639794
263 + 8639531 = 8639794
353 + 8639441 = 8639794

Showing the first eight; more decompositions exist.
