Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643550, here are decompositions:

11 + 8643539 = 8643550
23 + 8643527 = 8643550
29 + 8643521 = 8643550
107 + 8643443 = 8643550
191 + 8643359 = 8643550
233 + 8643317 = 8643550
263 + 8643287 = 8643550
269 + 8643281 = 8643550

Showing the first eight; more decompositions exist.
