subscribe to new node (gEth) while syncing and extracting logs

Question

Is it possible, to set up a new node using geth and subscripe to that node using web3js to save all transfers from the very beginning? Like could I scubribe to get "logs" events on a node that is currently syncing and newly setup using geth? I need all transfer events in a database and I have tried multiple ways to get this done which didnt work due to provider limitations and long taking pagination processes. This would be my last attempt doing it if possible.

if there are lots of events, you need to query by block range, otherwise you will wait for hours without getting a response.

In golang this would look like:

filter := ethereum.FilterQuery{}
filter.FromBlock = big.NewInt(block_num_from)
filter.ToBlock = big.NewInt(block_num_to)
topics := make([]common.Hash,0,1)
signature := common.BytesToHash(event_signature)
topics = append(topics,signature)
filter.Topics= append(filter.Topics,topics)
filter.Addresses = nil 
logs,err := eclient.FilterLogs(context.Background(),filter)
if err!= nil {
    os.Exit(1)
}
