Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700, here are decompositions:

  • 7 + 8693 = 8700
  • 11 + 8689 = 8700
  • 19 + 8681 = 8700
  • 23 + 8677 = 8700
  • 31 + 8669 = 8700
  • 37 + 8663 = 8700
  • 53 + 8647 = 8700
  • 59 + 8641 = 8700

Showing the first eight; more decompositions exist.
