Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608182, here are decompositions:

  • 13 + 31608169 = 31608182
  • 19 + 31608163 = 31608182
  • 211 + 31607971 = 31608182
  • 313 + 31607869 = 31608182
  • 499 + 31607683 = 31608182
  • 601 + 31607581 = 31608182
  • 631 + 31607551 = 31608182
  • 709 + 31607473 = 31608182

Showing the first eight; more decompositions exist.
