Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11742, here are decompositions:

  • 11 + 11731 = 11742
  • 23 + 11719 = 11742
  • 41 + 11701 = 11742
  • 43 + 11699 = 11742
  • 53 + 11689 = 11742
  • 61 + 11681 = 11742
  • 109 + 11633 = 11742
  • 149 + 11593 = 11742

Showing the first eight; more decompositions exist.
