Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33527440, here are decompositions:

  • 17 + 33527423 = 33527440
  • 29 + 33527411 = 33527440
  • 83 + 33527357 = 33527440
  • 101 + 33527339 = 33527440
  • 257 + 33527183 = 33527440
  • 269 + 33527171 = 33527440
  • 311 + 33527129 = 33527440
  • 467 + 33526973 = 33527440

Showing the first eight; more decompositions exist.
