Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643396, here are decompositions:

29 + 8643367 = 8643396
37 + 8643359 = 8643396
53 + 8643343 = 8643396
59 + 8643337 = 8643396
79 + 8643317 = 8643396
89 + 8643307 = 8643396
109 + 8643287 = 8643396
173 + 8643223 = 8643396

Showing the first eight; more decompositions exist.
