Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540660, here are decompositions:

  • 37 + 33540623 = 33540660
  • 53 + 33540607 = 33540660
  • 73 + 33540587 = 33540660
  • 79 + 33540581 = 33540660
  • 89 + 33540571 = 33540660
  • 103 + 33540557 = 33540660
  • 107 + 33540553 = 33540660
  • 157 + 33540503 = 33540660

Showing the first eight; more decompositions exist.
