Counterwallet Helper (https://forums.counterparty.io/t/is-it-possible-to-create-the-list-of-addresses-from-counterwallet-pass-phrase/1223/2) can work to a search depth of at least 10,000 addresses (I tested just now).
You could run it to an arbitrary depth, output result to file and go see a movie, then come back and check whether your address is or isn’t there.
