Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640956, here are decompositions:

7 + 8640949 = 8640956
67 + 8640889 = 8640956
73 + 8640883 = 8640956
97 + 8640859 = 8640956
139 + 8640817 = 8640956
157 + 8640799 = 8640956
223 + 8640733 = 8640956
277 + 8640679 = 8640956

Showing the first eight; more decompositions exist.
