C# App outputs PDF File. PDF Needs to be split...

I'm kind of new to C# and i'm looking for some help. I made an application that outputs a PDF file of about 50 pages. I need to have it create and save a new PDF file every 2 pages. So in the end i would have a total of 25 PDF files of 2 pages each instead of 1 PDF file of 50 pages. Can this be done?

Thanks,
Tony
