I have two line layers in PostgreSQL/PostGIS. I want to the select data which are not intersecting. When I am writing this query it is taking a lot of time. How can I make it faster and see the result?

<!-- language: sql -->

    SELECT Geometry into Qlayer5
    FROM qlayer4, egmap_20170316_tmc_polyline
    WHERE st_intersects(qlayer59.Geometry,egmap_20170316_tmc_polyline.geom) = false  

and I have also tried using right join but none of them giving output.

<!-- language: sql -->

    SELECT Geometry INTO Qlayer5
    FROM qlayer4
    RIGHT JOIN egmap_20170316_tmc_polyline ON
    st_intersects(qlayer59.Geometry,egmap_20170316_tmc_polyline.geom) = false
