Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99666, here are decompositions:

  • 5 + 99661 = 99666
  • 23 + 99643 = 99666
  • 43 + 99623 = 99666
  • 59 + 99607 = 99666
  • 89 + 99577 = 99666
  • 103 + 99563 = 99666
  • 107 + 99559 = 99666
  • 137 + 99529 = 99666

Showing the first eight; more decompositions exist.
