PDF Question...

When reading a PDF in a two page layout, is it possible to change which two pages are displayed? For example, I would like to see pages 13 and 14 side by side rather than 14 and 15. I have a field guide as a PDF that is frustrating to read because one page features animal illustrations and the next page features the animals' descriptions, but I can't seem to be able to match the corresponding pages in a two-page view in Preview and Adobe Reader.
