Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18322, here are decompositions:

11 + 18311 = 18322
53 + 18269 = 18322
71 + 18251 = 18322
89 + 18233 = 18322
131 + 18191 = 18322
173 + 18149 = 18322
179 + 18143 = 18322
191 + 18131 = 18322

Showing the first eight; more decompositions exist.
