Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639066, here are decompositions:

3 + 8639063 = 8639066
67 + 8638999 = 8639066
157 + 8638909 = 8639066
199 + 8638867 = 8639066
223 + 8638843 = 8639066
379 + 8638687 = 8639066
433 + 8638633 = 8639066
439 + 8638627 = 8639066

Showing the first eight; more decompositions exist.
