Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643344, here are decompositions:

7 + 8643337 = 8643344
37 + 8643307 = 8643344
163 + 8643181 = 8643344
211 + 8643133 = 8643344
223 + 8643121 = 8643344
331 + 8643013 = 8643344
397 + 8642947 = 8643344
433 + 8642911 = 8643344

Showing the first eight; more decompositions exist.
