Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87322, here are decompositions:

5 + 87317 = 87322
23 + 87299 = 87322
29 + 87293 = 87322
41 + 87281 = 87322
71 + 87251 = 87322
101 + 87221 = 87322
173 + 87149 = 87322
239 + 87083 = 87322

Showing the first eight; more decompositions exist.
