Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505440, here are decompositions:

  • 37 + 33505403 = 33505440
  • 47 + 33505393 = 33505440
  • 79 + 33505361 = 33505440
  • 103 + 33505337 = 33505440
  • 131 + 33505309 = 33505440
  • 139 + 33505301 = 33505440
  • 179 + 33505261 = 33505440
  • 193 + 33505247 = 33505440

Showing the first eight; more decompositions exist.
