Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524536, here are decompositions:

  • 3 + 31524533 = 31524536
  • 13 + 31524523 = 31524536
  • 19 + 31524517 = 31524536
  • 37 + 31524499 = 31524536
  • 67 + 31524469 = 31524536
  • 193 + 31524343 = 31524536
  • 313 + 31524223 = 31524536
  • 487 + 31524049 = 31524536

Showing the first eight; more decompositions exist.
