Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550560, here are decompositions:

  • 13 + 33550547 = 33550560
  • 47 + 33550513 = 33550560
  • 59 + 33550501 = 33550560
  • 79 + 33550481 = 33550560
  • 139 + 33550421 = 33550560
  • 167 + 33550393 = 33550560
  • 179 + 33550381 = 33550560
  • 223 + 33550337 = 33550560

Showing the first eight; more decompositions exist.
