Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538800, here are decompositions:

  • 13 + 33538787 = 33538800
  • 17 + 33538783 = 33538800
  • 37 + 33538763 = 33538800
  • 41 + 33538759 = 33538800
  • 59 + 33538741 = 33538800
  • 79 + 33538721 = 33538800
  • 89 + 33538711 = 33538800
  • 101 + 33538699 = 33538800

Showing the first eight; more decompositions exist.
