Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640996, here are decompositions:

19 + 8640977 = 8640996
29 + 8640967 = 8640996
47 + 8640949 = 8640996
107 + 8640889 = 8640996
109 + 8640887 = 8640996
113 + 8640883 = 8640996
137 + 8640859 = 8640996
173 + 8640823 = 8640996

Showing the first eight; more decompositions exist.
