Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11872, here are decompositions:

  • 5 + 11867 = 11872
  • 41 + 11831 = 11872
  • 59 + 11813 = 11872
  • 71 + 11801 = 11872
  • 83 + 11789 = 11872
  • 89 + 11783 = 11872
  • 173 + 11699 = 11872
  • 191 + 11681 = 11872

Showing the first eight; more decompositions exist.
