Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2860, here are decompositions:

  • 3 + 2857 = 2860
  • 17 + 2843 = 2860
  • 23 + 2837 = 2860
  • 41 + 2819 = 2860
  • 59 + 2801 = 2860
  • 71 + 2789 = 2860
  • 83 + 2777 = 2860
  • 107 + 2753 = 2860

Showing the first eight; more decompositions exist.
