If you have to, you can simply add more words. In practice, most real life systems use secure password hashing algorithms, captchas, and other mechanisms to stop password cracking. It is unlikely that your attacker can reach anywhere close to a million guesses a second, and so a four word password (from the large list) is probably sufficient in real life.
