Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25872, here are decompositions:

  • 5 + 25867 = 25872
  • 23 + 25849 = 25872
  • 31 + 25841 = 25872
  • 53 + 25819 = 25872
  • 71 + 25801 = 25872
  • 73 + 25799 = 25872
  • 79 + 25793 = 25872
  • 101 + 25771 = 25872

Showing the first eight; more decompositions exist.
