Postgresql – Postgis distance filter does not work as expected

I have a issue with simple PostGIS query.

Here is a query:

SELECT 
  id,
  location,
  ST_Distance_Sphere(location, ST_MakePoint(21.012228699999998, 52.2296756)) AS distance
FROM pins
WHERE
  ST_Distance_Sphere(location, ST_MakePoint(21.012228699999998, 52.2296756)) > 6008000.1836031
ORDER BY distance ASC, id ASC 
LIMIT 11;

And here is a result:

id  |                      location                      |     distance

For some reason row with id = 58 is returned and its distance is 6008000.1836031 despite I've used where filter ST_Distance_Sphere(location, ST_MakePoint(21.012228699999998, 52.2296756)) > 6008000.1836031

I guess Postgis calculates distance with greater precision?
How I can avoid this situation?
