Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66936, here are decompositions:

  • 5 + 66931 = 66936
  • 13 + 66923 = 66936
  • 17 + 66919 = 66936
  • 47 + 66889 = 66936
  • 53 + 66883 = 66936
  • 59 + 66877 = 66936
  • 73 + 66863 = 66936
  • 83 + 66853 = 66936

Showing the first eight; more decompositions exist.
