Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33516808, here are decompositions:

  • 41 + 33516767 = 33516808
  • 47 + 33516761 = 33516808
  • 317 + 33516491 = 33516808
  • 359 + 33516449 = 33516808
  • 401 + 33516407 = 33516808
  • 467 + 33516341 = 33516808
  • 491 + 33516317 = 33516808
  • 557 + 33516251 = 33516808

Showing the first eight; more decompositions exist.
