Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524664, here are decompositions:

  • 23 + 31524641 = 31524664
  • 131 + 31524533 = 31524664
  • 467 + 31524197 = 31524664
  • 503 + 31524161 = 31524664
  • 557 + 31524107 = 31524664
  • 617 + 31524047 = 31524664
  • 641 + 31524023 = 31524664
  • 653 + 31524011 = 31524664

Showing the first eight; more decompositions exist.
