Yes, rewriting the query with an IN clause was also my first approach, but I didn't help much. 
The Query plan did change a little bit but the performance was not impacted.
 
CREATE INDEX idx_arcstatus_le1 ON schema.logtable ( archivestatus ) where (archivestatus <= 1)
ANALYZE  schema.logtable

I assume (4000,4001,4002) are just example-values and that they might be anything? Else you can just include them in your partial-index.
