List supplemental results only

Is there a way to do this?

[SEOPTI]

I run a site with more than 15,000 pages. The site: command starts to show supplemental results beginning with position 980, so I see 20 supplemental.

What would be the best way to know which pages are supplemental starting at position 1,000+?

The site:www.domain.com -inurl:www search usually lists a lot of Supplemental Results, but it isn't clear to me whether those are the supplemental old results for the older version of the content for URLs that also show in the normal index for their current content, or whether they are for URLs that are always supplemental whatever the search criteria because they are URLs that have already been redirected or 404 for quite some time already.

There is no use in blindly listing Supplemental Results without investigating to see if they are results that Google already has on their "delete in a year" list (not harmful), or they still represent live duplicate content with multiple "200 OK" URLs delivering the same content (potentially harmful).
