I am not sure how to achieve this. Please suggest any preprocess or backend feature which can do this?
The easiest is probably the comment from @No SSsweat
Another easy option is to place the view in each region and hide the pager/content using CSS depending on region.
The neater solution is to use some php code, the drupal way, probably someone has already done this for you, so look for a drupal contributed module related to view and pager or paging, and layout, those would probably be my keywords for a search.
