Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550400, here are decompositions:

  • 7 + 33550393 = 33550400
  • 19 + 33550381 = 33550400
  • 73 + 33550327 = 33550400
  • 199 + 33550201 = 33550400
  • 211 + 33550189 = 33550400
  • 283 + 33550117 = 33550400
  • 349 + 33550051 = 33550400
  • 379 + 33550021 = 33550400

Showing the first eight; more decompositions exist.
