Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643374, here are decompositions:

7 + 8643367 = 8643374
31 + 8643343 = 8643374
37 + 8643337 = 8643374
67 + 8643307 = 8643374
151 + 8643223 = 8643374
163 + 8643211 = 8643374
193 + 8643181 = 8643374
241 + 8643133 = 8643374

Showing the first eight; more decompositions exist.
