Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643326, here are decompositions:

19 + 8643307 = 8643326
103 + 8643223 = 8643326
127 + 8643199 = 8643326
193 + 8643133 = 8643326
313 + 8643013 = 8643326
337 + 8642989 = 8643326
379 + 8642947 = 8643326
463 + 8642863 = 8643326

Showing the first eight; more decompositions exist.
