Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643426, here are decompositions:

17 + 8643409 = 8643426
59 + 8643367 = 8643426
67 + 8643359 = 8643426
83 + 8643343 = 8643426
89 + 8643337 = 8643426
109 + 8643317 = 8643426
139 + 8643287 = 8643426
227 + 8643199 = 8643426

Showing the first eight; more decompositions exist.
