Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644980, here are decompositions:

17 + 8644963 = 8644980
23 + 8644957 = 8644980
31 + 8644949 = 8644980
53 + 8644927 = 8644980
61 + 8644919 = 8644980
67 + 8644913 = 8644980
107 + 8644873 = 8644980
137 + 8644843 = 8644980

Showing the first eight; more decompositions exist.
