Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8222, here are decompositions:

  • 3 + 8219 = 8222
  • 13 + 8209 = 8222
  • 31 + 8191 = 8222
  • 43 + 8179 = 8222
  • 61 + 8161 = 8222
  • 163 + 8059 = 8222
  • 211 + 8011 = 8222
  • 229 + 7993 = 8222

Showing the first eight; more decompositions exist.
