Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 860, here are decompositions:

  • 3 + 857 = 860
  • 7 + 853 = 860
  • 31 + 829 = 860
  • 37 + 823 = 860
  • 73 + 787 = 860
  • 103 + 757 = 860
  • 109 + 751 = 860
  • 127 + 733 = 860

Showing the first eight; more decompositions exist.
