Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524064, here are decompositions:

  • 17 + 31524047 = 31524064
  • 41 + 31524023 = 31524064
  • 53 + 31524011 = 31524064
  • 263 + 31523801 = 31524064
  • 311 + 31523753 = 31524064
  • 431 + 31523633 = 31524064
  • 587 + 31523477 = 31524064
  • 653 + 31523411 = 31524064

Showing the first eight; more decompositions exist.
