Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23730, here are decompositions:

  • 11 + 23719 = 23730
  • 41 + 23689 = 23730
  • 43 + 23687 = 23730
  • 53 + 23677 = 23730
  • 59 + 23671 = 23730
  • 61 + 23669 = 23730
  • 67 + 23663 = 23730
  • 97 + 23633 = 23730

Showing the first eight; more decompositions exist.
