Oracle condition to limit sql query

Question

I have this sql for oracle database. How can I write the condition to get the data between 5 and 30? Based on the values from sql I want to make a datagrid in php with pagination.

"select c.case_id as NGM_ID,   
       s.NE_PRIORITAET as NE_PRIO,
       case substr(s.NE_ID, 2,1)

Like this:

select * from (
select ROW_NUMBER() OVER(order by c.CREATION_TIME desc) rn, c.case_id as NGM_ID,

         when '0' then 'Zentrale'

         when '2' then 'Nord'
