Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524528, here are decompositions:

  • 5 + 31524523 = 31524528
  • 11 + 31524517 = 31524528
  • 19 + 31524509 = 31524528
  • 29 + 31524499 = 31524528
  • 59 + 31524469 = 31524528
  • 109 + 31524419 = 31524528
  • 197 + 31524331 = 31524528
  • 227 + 31524301 = 31524528

Showing the first eight; more decompositions exist.
