Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525724, here are decompositions:

  • 7 + 31525717 = 31525724
  • 37 + 31525687 = 31525724
  • 67 + 31525657 = 31525724
  • 73 + 31525651 = 31525724
  • 157 + 31525567 = 31525724
  • 277 + 31525447 = 31525724
  • 457 + 31525267 = 31525724
  • 463 + 31525261 = 31525724

Showing the first eight; more decompositions exist.
