Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640968, here are decompositions:

19 + 8640949 = 8640968
79 + 8640889 = 8640968
97 + 8640871 = 8640968
109 + 8640859 = 8640968
151 + 8640817 = 8640968
181 + 8640787 = 8640968
229 + 8640739 = 8640968
277 + 8640691 = 8640968

Showing the first eight; more decompositions exist.
