Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481728, here are decompositions:

  • 101 + 33481627 = 33481728
  • 131 + 33481597 = 33481728
  • 151 + 33481577 = 33481728
  • 157 + 33481571 = 33481728
  • 179 + 33481549 = 33481728
  • 229 + 33481499 = 33481728
  • 257 + 33481471 = 33481728
  • 331 + 33481397 = 33481728

Showing the first eight; more decompositions exist.
