Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644960, here are decompositions:

3 + 8644957 = 8644960
11 + 8644949 = 8644960
41 + 8644919 = 8644960
47 + 8644913 = 8644960
179 + 8644781 = 8644960
257 + 8644703 = 8644960
281 + 8644679 = 8644960
353 + 8644607 = 8644960

Showing the first eight; more decompositions exist.
