Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639764, here are decompositions:

11 + 8639753 = 8639764
17 + 8639747 = 8639764
53 + 8639711 = 8639764
101 + 8639663 = 8639764
167 + 8639597 = 8639764
173 + 8639591 = 8639764
197 + 8639567 = 8639764
233 + 8639531 = 8639764

Showing the first eight; more decompositions exist.
