Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8458, here are decompositions:

  • 11 + 8447 = 8458
  • 29 + 8429 = 8458
  • 71 + 8387 = 8458
  • 89 + 8369 = 8458
  • 167 + 8291 = 8458
  • 227 + 8231 = 8458
  • 239 + 8219 = 8458
  • 311 + 8147 = 8458

Showing the first eight; more decompositions exist.
