Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540440, here are decompositions:

  • 13 + 33540427 = 33540440
  • 19 + 33540421 = 33540440
  • 67 + 33540373 = 33540440
  • 97 + 33540343 = 33540440
  • 151 + 33540289 = 33540440
  • 163 + 33540277 = 33540440
  • 181 + 33540259 = 33540440
  • 211 + 33540229 = 33540440

Showing the first eight; more decompositions exist.
