Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643366, here are decompositions:

7 + 8643359 = 8643366
23 + 8643343 = 8643366
29 + 8643337 = 8643366
59 + 8643307 = 8643366
79 + 8643287 = 8643366
157 + 8643209 = 8643366
167 + 8643199 = 8643366
223 + 8643143 = 8643366

Showing the first eight; more decompositions exist.
