Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640916, here are decompositions:

5 + 8640911 = 8640916
29 + 8640887 = 8640916
149 + 8640767 = 8640916
197 + 8640719 = 8640916
227 + 8640689 = 8640916
233 + 8640683 = 8640916
509 + 8640407 = 8640916
587 + 8640329 = 8640916

Showing the first eight; more decompositions exist.
