Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540920, here are decompositions:

  • 19 + 33540901 = 33540920
  • 31 + 33540889 = 33540920
  • 109 + 33540811 = 33540920
  • 157 + 33540763 = 33540920
  • 223 + 33540697 = 33540920
  • 229 + 33540691 = 33540920
  • 313 + 33540607 = 33540920
  • 349 + 33540571 = 33540920

Showing the first eight; more decompositions exist.
