Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524712, here are decompositions:

  • 71 + 31524641 = 31524712
  • 179 + 31524533 = 31524712
  • 293 + 31524419 = 31524712
  • 419 + 31524293 = 31524712
  • 701 + 31524011 = 31524712
  • 773 + 31523939 = 31524712
  • 911 + 31523801 = 31524712
  • 1061 + 31523651 = 31524712

Showing the first eight; more decompositions exist.
