Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643356, here are decompositions:

13 + 8643343 = 8643356
19 + 8643337 = 8643356
157 + 8643199 = 8643356
223 + 8643133 = 8643356
367 + 8642989 = 8643356
409 + 8642947 = 8643356
499 + 8642857 = 8643356
823 + 8642533 = 8643356

Showing the first eight; more decompositions exist.
