Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550240, here are decompositions:

  • 11 + 33550229 = 33550240
  • 131 + 33550109 = 33550240
  • 197 + 33550043 = 33550240
  • 257 + 33549983 = 33550240
  • 263 + 33549977 = 33550240
  • 419 + 33549821 = 33550240
  • 443 + 33549797 = 33550240
  • 461 + 33549779 = 33550240

Showing the first eight; more decompositions exist.
