Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61728, here are decompositions:

  • 5 + 61723 = 61728
  • 11 + 61717 = 61728
  • 41 + 61687 = 61728
  • 47 + 61681 = 61728
  • 61 + 61667 = 61728
  • 71 + 61657 = 61728
  • 97 + 61631 = 61728
  • 101 + 61627 = 61728

Showing the first eight; more decompositions exist.
