Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8800, here are decompositions:

  • 17 + 8783 = 8800
  • 47 + 8753 = 8800
  • 53 + 8747 = 8800
  • 59 + 8741 = 8800
  • 101 + 8699 = 8800
  • 107 + 8693 = 8800
  • 131 + 8669 = 8800
  • 137 + 8663 = 8800

Showing the first eight; more decompositions exist.
