You can't brute-force that keyspace. Only thing you can do is mask attack that is very selective, and/or use maskprocessor to create some specific wordlists that have patterns (repeated digits like '9999', repeated patterns of digits like '123123123', etc). If you have a small number of patterns, you could use those with a hybrid attack to combine those patterns with a left-side or right-side mask. This is assuming the passwords were chosen by humans.
If they were randomly generated, not based on any pattern (i.e. not like phone numbers, where there is a limited set of valid patterns), then good luck... It's nearly impossible to even get lucky if they're truly random.
