Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512496, here are decompositions:

  • 17 + 31512479 = 31512496
  • 137 + 31512359 = 31512496
  • 149 + 31512347 = 31512496
  • 383 + 31512113 = 31512496
  • 479 + 31512017 = 31512496
  • 503 + 31511993 = 31512496
  • 557 + 31511939 = 31512496
  • 563 + 31511933 = 31512496

Showing the first eight; more decompositions exist.
