Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545934, here are decompositions:

  • 11 + 31545923 = 31545934
  • 47 + 31545887 = 31545934
  • 191 + 31545743 = 31545934
  • 197 + 31545737 = 31545934
  • 293 + 31545641 = 31545934
  • 311 + 31545623 = 31545934
  • 617 + 31545317 = 31545934
  • 647 + 31545287 = 31545934

Showing the first eight; more decompositions exist.
