You show the recovered key and plaintext and demonstrate that they match the ciphertext.
The chance that several gigabytes of encrypted data accidentally happen to decrypt with wrong key to a different several gigabytes of perfectly valid data is rather slim, which means that any key which produces valid data is the key you are looking for.
