Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641282, here are decompositions:

71 + 8641211 = 8641282
149 + 8641133 = 8641282
521 + 8640761 = 8641282
563 + 8640719 = 8641282
569 + 8640713 = 8641282
593 + 8640689 = 8641282
599 + 8640683 = 8641282
863 + 8640419 = 8641282

Showing the first eight; more decompositions exist.
