Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81322, here are decompositions:

23 + 81299 = 81322
29 + 81293 = 81322
41 + 81281 = 81322
83 + 81239 = 81322
89 + 81233 = 81322
149 + 81173 = 81322
191 + 81131 = 81322
239 + 81083 = 81322

Showing the first eight; more decompositions exist.
