Something like (adjust the limits as you want):
SQL> select sysdate-59+10*level start_date, sysdate-50+10*level from dual connect by level <= 5
  2  /
START_DATE  SYSDATE-50+
----------- -----------
19-APR-2016 28-APR-2016
29-APR-2016 08-MAY-2016
09-MAY-2016 18-MAY-2016
19-MAY-2016 28-MAY-2016
29-MAY-2016 07-JUN-2016

See above.
You had the answer.
What is your purpose to repeat your question again and again?

The desired results that you posted are actually intervals of 11 days for 66 days, starting with sysdate and going backwards.

SCOTT@orcl_12.1.0.2.0> select  (sysdate+1)-(11*level) start_date,
  2  	     (sysdate+11)-(11*level) end_date
  3  from    dual
  4  connect by level <= 6
  5  /

START_DATE END_DATE
---------- ----------
28/05/2016 07/06/2016
17/05/2016 27/05/2016
06/05/2016 16/05/2016
25/04/2016 05/05/2016
14/04/2016 24/04/2016
03/04/2016 13/04/2016

Please consider, my last date range (6/4/2016 - 13/4/2016) is not for 10 days.
