Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18222, here are decompositions:

  • 5 + 18217 = 18222
  • 11 + 18211 = 18222
  • 23 + 18199 = 18222
  • 31 + 18191 = 18222
  • 41 + 18181 = 18222
  • 53 + 18169 = 18222
  • 73 + 18149 = 18222
  • 79 + 18143 = 18222

Showing the first eight; more decompositions exist.
