Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642322, here are decompositions:

19 + 8642303 = 8642322
41 + 8642281 = 8642322
149 + 8642173 = 8642322
163 + 8642159 = 8642322
181 + 8642141 = 8642322
211 + 8642111 = 8642322
223 + 8642099 = 8642322
263 + 8642059 = 8642322

Showing the first eight; more decompositions exist.
