In a public-key scheme, not the whole msg is encrypted with the public key; since the algoritme for this encryption is more complex (read slower) then encryption with a symetric-key formula.
The public key is used to hide the symetric key, which is used to encrypt the whole msg. The backdoor would be the symetric key, encrypted with the public key of "the government".
