Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540160, here are decompositions:

  • 53 + 33540107 = 33540160
  • 89 + 33540071 = 33540160
  • 107 + 33540053 = 33540160
  • 149 + 33540011 = 33540160
  • 389 + 33539771 = 33540160
  • 419 + 33539741 = 33540160
  • 491 + 33539669 = 33540160
  • 557 + 33539603 = 33540160

Showing the first eight; more decompositions exist.
