Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540918, here are decompositions:

  • 17 + 33540901 = 33540918
  • 29 + 33540889 = 33540918
  • 31 + 33540887 = 33540918
  • 97 + 33540821 = 33540918
  • 107 + 33540811 = 33540918
  • 211 + 33540707 = 33540918
  • 227 + 33540691 = 33540918
  • 311 + 33540607 = 33540918

Showing the first eight; more decompositions exist.
