Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18434, here are decompositions:

  • 7 + 18427 = 18434
  • 37 + 18397 = 18434
  • 67 + 18367 = 18434
  • 127 + 18307 = 18434
  • 181 + 18253 = 18434
  • 211 + 18223 = 18434
  • 223 + 18211 = 18434
  • 307 + 18127 = 18434

Showing the first eight; more decompositions exist.
