Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18422, here are decompositions:

43 + 18379 = 18422
109 + 18313 = 18422
193 + 18229 = 18422
199 + 18223 = 18422
211 + 18211 = 18422
223 + 18199 = 18422
241 + 18181 = 18422
373 + 18049 = 18422

Showing the first eight; more decompositions exist.
