Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524512, here are decompositions:

  • 3 + 31524509 = 31524512
  • 13 + 31524499 = 31524512
  • 43 + 31524469 = 31524512
  • 109 + 31524403 = 31524512
  • 181 + 31524331 = 31524512
  • 211 + 31524301 = 31524512
  • 241 + 31524271 = 31524512
  • 379 + 31524133 = 31524512

Showing the first eight; more decompositions exist.
