Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533516, here are decompositions:

  • 5 + 31533511 = 31533516
  • 17 + 31533499 = 31533516
  • 19 + 31533497 = 31533516
  • 67 + 31533449 = 31533516
  • 103 + 31533413 = 31533516
  • 107 + 31533409 = 31533516
  • 127 + 31533389 = 31533516
  • 137 + 31533379 = 31533516

Showing the first eight; more decompositions exist.
