Export single page PDF, with page number for name

Not sure if this is best done in InDesign or Acrobat, I'm starting here.

I have a 100+ page document. I need each page to be a separate PDF. However, I need the PDFs to be named the page number. My page numbers for this document start with 3781, so the first page needs to be 3781.pdf (not [my document]_1.pdf)

I'm thinking a script is the best way??

Thanks,

Lisa
