Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33579320, here are decompositions:

  • 37 + 33579283 = 33579320
  • 43 + 33579277 = 33579320
  • 109 + 33579211 = 33579320
  • 199 + 33579121 = 33579320
  • 409 + 33578911 = 33579320
  • 433 + 33578887 = 33579320
  • 457 + 33578863 = 33579320
  • 547 + 33578773 = 33579320

Showing the first eight; more decompositions exist.
