Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471808, here are decompositions:

  • 5 + 33471803 = 33471808
  • 89 + 33471719 = 33471808
  • 101 + 33471707 = 33471808
  • 131 + 33471677 = 33471808
  • 179 + 33471629 = 33471808
  • 311 + 33471497 = 33471808
  • 317 + 33471491 = 33471808
  • 449 + 33471359 = 33471808

Showing the first eight; more decompositions exist.
