Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566440, here are decompositions:

  • 41 + 33566399 = 33566440
  • 53 + 33566387 = 33566440
  • 107 + 33566333 = 33566440
  • 113 + 33566327 = 33566440
  • 137 + 33566303 = 33566440
  • 239 + 33566201 = 33566440
  • 251 + 33566189 = 33566440
  • 317 + 33566123 = 33566440

Showing the first eight; more decompositions exist.
