Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8398, here are decompositions:

  • 11 + 8387 = 8398
  • 29 + 8369 = 8398
  • 101 + 8297 = 8398
  • 107 + 8291 = 8398
  • 167 + 8231 = 8398
  • 179 + 8219 = 8398
  • 227 + 8171 = 8398
  • 251 + 8147 = 8398

Showing the first eight; more decompositions exist.
