Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 936, here are decompositions:

  • 7 + 929 = 936
  • 17 + 919 = 936
  • 29 + 907 = 936
  • 53 + 883 = 936
  • 59 + 877 = 936
  • 73 + 863 = 936
  • 79 + 857 = 936
  • 83 + 853 = 936

Showing the first eight; more decompositions exist.
