Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523720, here are decompositions:

  • 23 + 33523697 = 33523720
  • 137 + 33523583 = 33523720
  • 257 + 33523463 = 33523720
  • 311 + 33523409 = 33523720
  • 449 + 33523271 = 33523720
  • 467 + 33523253 = 33523720
  • 479 + 33523241 = 33523720
  • 491 + 33523229 = 33523720

Showing the first eight; more decompositions exist.
