Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545794, here are decompositions:

  • 31 + 31545763 = 31545794
  • 127 + 31545667 = 31545794
  • 307 + 31545487 = 31545794
  • 421 + 31545373 = 31545794
  • 463 + 31545331 = 31545794
  • 613 + 31545181 = 31545794
  • 727 + 31545067 = 31545794
  • 733 + 31545061 = 31545794

Showing the first eight; more decompositions exist.
