Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99690, here are decompositions:

  • 11 + 99679 = 99690
  • 23 + 99667 = 99690
  • 29 + 99661 = 99690
  • 47 + 99643 = 99690
  • 67 + 99623 = 99690
  • 79 + 99611 = 99690
  • 83 + 99607 = 99690
  • 109 + 99581 = 99690

Showing the first eight; more decompositions exist.
