Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556800, here are decompositions:

  • 31 + 33556769 = 33556800
  • 89 + 33556711 = 33556800
  • 127 + 33556673 = 33556800
  • 229 + 33556571 = 33556800
  • 241 + 33556559 = 33556800
  • 269 + 33556531 = 33556800
  • 271 + 33556529 = 33556800
  • 293 + 33556507 = 33556800

Showing the first eight; more decompositions exist.
