Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33510640, here are decompositions:

  • 41 + 33510599 = 33510640
  • 173 + 33510467 = 33510640
  • 179 + 33510461 = 33510640
  • 197 + 33510443 = 33510640
  • 227 + 33510413 = 33510640
  • 239 + 33510401 = 33510640
  • 281 + 33510359 = 33510640
  • 419 + 33510221 = 33510640

Showing the first eight; more decompositions exist.
