SELECT with OFFSET oracle

[demoniac18]

I need to do SELECT query from java code on table that contains 1kkk rows , so the result set will be near 1kk rows. thats why I need to limit it, and run select query many times and each time to retrieve 10k rows only. After I get 10k rows I update it so in the next SELECT they wont be retrieved.
The problem is - in each select oracle looking from first row in the table so it reduces the performance.
How can I use OFFSET for avoiding oracle looking from first row and pass over already updated rows?

To avoid seq scan (looking from the first row) you can define an index on the table. Do you have any indexes defined?

Yes, I have default rowid in oracle as index . I can also store in java code rowid of last updated row.
So can I use in WHERE clause rowid < last_updated_ro wid ?
