Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2768, here are decompositions:

  • 19 + 2749 = 2768
  • 37 + 2731 = 2768
  • 61 + 2707 = 2768
  • 79 + 2689 = 2768
  • 97 + 2671 = 2768
  • 109 + 2659 = 2768
  • 151 + 2617 = 2768
  • 211 + 2557 = 2768

Showing the first eight; more decompositions exist.
