Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99660, here are decompositions:

  • 17 + 99643 = 99660
  • 37 + 99623 = 99660
  • 53 + 99607 = 99660
  • 79 + 99581 = 99660
  • 83 + 99577 = 99660
  • 89 + 99571 = 99660
  • 97 + 99563 = 99660
  • 101 + 99559 = 99660

Showing the first eight; more decompositions exist.
