Recover BIP38 passphrase with some given information?

[boozer]

I used https://liteaddress.org/ to generate some keys.  I put my passphrase in a truecrypt container and seem to have forgot my truecrypt p/w     

However, I have made a transaction, so for one address I have the private key and BIP38 encrypted private key....   Since I have the BIP38 encrypted key and the private key after decryption, can I recover my pass phrase?

remembered my truecrypt p/w finally... but curious if you can get the passphrase if you have only the BIP38 encrypted and decrypted private key.
