Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644986, here are decompositions:

23 + 8644963 = 8644986
29 + 8644957 = 8644986
37 + 8644949 = 8644986
59 + 8644927 = 8644986
67 + 8644919 = 8644986
73 + 8644913 = 8644986
83 + 8644903 = 8644986
113 + 8644873 = 8644986

Showing the first eight; more decompositions exist.
