Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23918, here are decompositions:

  • 7 + 23911 = 23918
  • 19 + 23899 = 23918
  • 31 + 23887 = 23918
  • 61 + 23857 = 23918
  • 151 + 23767 = 23918
  • 157 + 23761 = 23918
  • 199 + 23719 = 23918
  • 229 + 23689 = 23918

Showing the first eight; more decompositions exist.
