I’d like to create a page displaying only expired Entries, but having problems when it comes to paginating the results as my current solution still returns the current Entries.
I’ve taken some inspiration from an old EE1 thread: http://ellislab.com/forums/viewthread/87987/ to conditionally exclude current Entries from the exp:channel:entries loop:

{exp:channel:entries channel="news" show_expired="yes" dynamic="no" limit="4" paginate="bottom"}

{if current_time > expiration_date && expiration_date}
{title}
<hr>
{/if}
{paginate}
Page {current_page} of {total_pages} pages {pagination_links}
{/paginate}
{/exp:channel:entries}

Is there a way to accomplish the above so that the pagination shows only the expired Entries? 
Any help appreciated, thanks!
