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.
