Unable to load Huge 2.1GB Pdf to split it

I am trying to split a huge 2.1gb pdf document into smaller 200 page pdfs.

I am unable to load the document into either the

ASPOSE.PDF.Document or the Aspose.Pdf.Facades.PdfFileEditor

I am coding on a Win 8.1 machine with Visual Studio 2015. My machine has 24gb of Ram and I am only using 10gb. When trying to load the document, the memory does not increase like I would expect to see. It stays constant, like its not even trying to read the file.

I cannot share the document, due to it being a sensitive document protected by our agency. I am trying to see if I can install adobe pro now to see if i can split it.
