Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12406, here are decompositions:

  • 5 + 12401 = 12406
  • 29 + 12377 = 12406
  • 59 + 12347 = 12406
  • 83 + 12323 = 12406
  • 137 + 12269 = 12406
  • 167 + 12239 = 12406
  • 179 + 12227 = 12406
  • 257 + 12149 = 12406

Showing the first eight; more decompositions exist.
