Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643566, here are decompositions:

3 + 8643563 = 8643566
79 + 8643487 = 8643566
109 + 8643457 = 8643566
157 + 8643409 = 8643566
199 + 8643367 = 8643566
223 + 8643343 = 8643566
229 + 8643337 = 8643566
367 + 8643199 = 8643566

Showing the first eight; more decompositions exist.
