Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640924, here are decompositions:

13 + 8640911 = 8640924
37 + 8640887 = 8640924
41 + 8640883 = 8640924
53 + 8640871 = 8640924
101 + 8640823 = 8640924
107 + 8640817 = 8640924
137 + 8640787 = 8640924
157 + 8640767 = 8640924

Showing the first eight; more decompositions exist.
