Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643318, here are decompositions:

11 + 8643307 = 8643318
31 + 8643287 = 8643318
37 + 8643281 = 8643318
107 + 8643211 = 8643318
109 + 8643209 = 8643318
137 + 8643181 = 8643318
181 + 8643137 = 8643318
197 + 8643121 = 8643318

Showing the first eight; more decompositions exist.
