Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578728, here are decompositions:

  • 41 + 33578687 = 33578728
  • 251 + 33578477 = 33578728
  • 317 + 33578411 = 33578728
  • 461 + 33578267 = 33578728
  • 467 + 33578261 = 33578728
  • 509 + 33578219 = 33578728
  • 641 + 33578087 = 33578728
  • 761 + 33577967 = 33578728

Showing the first eight; more decompositions exist.
