Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2836, here are decompositions:

  • 3 + 2833 = 2836
  • 17 + 2819 = 2836
  • 47 + 2789 = 2836
  • 59 + 2777 = 2836
  • 83 + 2753 = 2836
  • 107 + 2729 = 2836
  • 137 + 2699 = 2836
  • 149 + 2687 = 2836

Showing the first eight; more decompositions exist.
