Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643330, here are decompositions:

13 + 8643317 = 8643330
23 + 8643307 = 8643330
43 + 8643287 = 8643330
107 + 8643223 = 8643330
131 + 8643199 = 8643330
149 + 8643181 = 8643330
181 + 8643149 = 8643330
193 + 8643137 = 8643330

Showing the first eight; more decompositions exist.
