Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524256, here are decompositions:

  • 59 + 31524197 = 31524256
  • 89 + 31524167 = 31524256
  • 149 + 31524107 = 31524256
  • 233 + 31524023 = 31524256
  • 317 + 31523939 = 31524256
  • 503 + 31523753 = 31524256
  • 587 + 31523669 = 31524256
  • 677 + 31523579 = 31524256

Showing the first eight; more decompositions exist.
