somewhere between 1 and 31^58 (31 because the longest bitcoin address in base58 can be 35 characters and you fixed the first 4 characters).
if you also fix the checksum which is i believe a little less than 5 characters then the number shrinks by a lot but still can be more than just one since it is a 4 byte collision with only a couple of initial bytes of the data set.
any particular reason you are asking this?
There is a FOMO brewing...

to understand more and by chance this checksum is calculated?
thanks for response.

then you have to look into how this type of addresses are created (
https://en.bitcoin.it/wiki/Technical_background_of_Bitcoin_addresses
) and also the encoding used in them (
https://en.bitcoin.it/wiki/Base58Check_encoding
). going in reverse won't answer your questions.
in short the checksum is calculated by taking the 21 bytes input (version + result of HASH160) and performing 2 times SHA256 on it then taking the first 4 bytes.

The same question was recently asked in this thread:

I think it will provide the information you might be looking for.

Based off Vanitygen:
The number of all BTC addresses starting with a prefix indicated is:
2^160 / (difficulty of that vanity address).
Then you need a software to compute the difficulty.
12c6 --> difficulty = 77178 --> number of all BTC addresses starting
12c6 --> 2^160 / 77178 =
18,936,764,846,600,105,188,054,689,584,030,203,162,247,435 that begins with 12c6
