Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643322, here are decompositions:

5 + 8643317 = 8643322
41 + 8643281 = 8643322
113 + 8643209 = 8643322
173 + 8643149 = 8643322
179 + 8643143 = 8643322
239 + 8643083 = 8643322
263 + 8643059 = 8643322
269 + 8643053 = 8643322

Showing the first eight; more decompositions exist.
