Extending that to all known digits would be a fun technical challenge. I once wrote a code to calculate positions where k subsequent decimal digits equal to the position index itself [1], but I had no storage to spare so I instead used a stream of digits from the public GCP dataset [2]. You would eventually want to try this approach if you are like me (i.e. don't want to pay for two-digit-TB storage).
