Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42768, here are decompositions:

  • 17 + 42751 = 42768
  • 31 + 42737 = 42768
  • 41 + 42727 = 42768
  • 59 + 42709 = 42768
  • 67 + 42701 = 42768
  • 71 + 42697 = 42768
  • 79 + 42689 = 42768
  • 101 + 42667 = 42768

Showing the first eight; more decompositions exist.
