Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643498, here are decompositions:

11 + 8643487 = 8643498
41 + 8643457 = 8643498
89 + 8643409 = 8643498
131 + 8643367 = 8643498
139 + 8643359 = 8643498
181 + 8643317 = 8643498
191 + 8643307 = 8643498
211 + 8643287 = 8643498

Showing the first eight; more decompositions exist.
