Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644970, here are decompositions:

7 + 8644963 = 8644970
13 + 8644957 = 8644970
43 + 8644927 = 8644970
67 + 8644903 = 8644970
97 + 8644873 = 8644970
109 + 8644861 = 8644970
127 + 8644843 = 8644970
199 + 8644771 = 8644970

Showing the first eight; more decompositions exist.
