Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737720, here are decompositions:

  • 3 + 8737717 = 8737720
  • 11 + 8737709 = 8737720
  • 23 + 8737697 = 8737720
  • 53 + 8737667 = 8737720
  • 137 + 8737583 = 8737720
  • 149 + 8737571 = 8737720
  • 191 + 8737529 = 8737720
  • 197 + 8737523 = 8737720

Showing the first eight; more decompositions exist.
