Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643224, here are decompositions:

13 + 8643211 = 8643224
43 + 8643181 = 8643224
103 + 8643121 = 8643224
211 + 8643013 = 8643224
277 + 8642947 = 8643224
313 + 8642911 = 8643224
367 + 8642857 = 8643224
463 + 8642761 = 8643224

Showing the first eight; more decompositions exist.
