Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644966, here are decompositions:

3 + 8644963 = 8644966
17 + 8644949 = 8644966
47 + 8644919 = 8644966
53 + 8644913 = 8644966
167 + 8644799 = 8644966
263 + 8644703 = 8644966
359 + 8644607 = 8644966
467 + 8644499 = 8644966

Showing the first eight; more decompositions exist.
