Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524118, here are decompositions:

  • 11 + 31524107 = 31524118
  • 71 + 31524047 = 31524118
  • 107 + 31524011 = 31524118
  • 179 + 31523939 = 31524118
  • 317 + 31523801 = 31524118
  • 449 + 31523669 = 31524118
  • 467 + 31523651 = 31524118
  • 641 + 31523477 = 31524118

Showing the first eight; more decompositions exist.
