Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79728, here are decompositions:

  • 29 + 79699 = 79728
  • 31 + 79697 = 79728
  • 37 + 79691 = 79728
  • 41 + 79687 = 79728
  • 59 + 79669 = 79728
  • 71 + 79657 = 79728
  • 97 + 79631 = 79728
  • 101 + 79627 = 79728

Showing the first eight; more decompositions exist.
