Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524656, here are decompositions:

  • 13 + 31524643 = 31524656
  • 139 + 31524517 = 31524656
  • 157 + 31524499 = 31524656
  • 313 + 31524343 = 31524656
  • 379 + 31524277 = 31524656
  • 433 + 31524223 = 31524656
  • 463 + 31524193 = 31524656
  • 523 + 31524133 = 31524656

Showing the first eight; more decompositions exist.
