KWord is a KDE application that has a pdf “import” feature which lets you import either entire pdf documents or just a few pages from a pdf document while preserving the formatting! Of course - this only works for pdf documents which are not scanned images of pages.
Installing kword
sudo apt-get install kword
Start the import using the “File” -> “Import” option in the main KWord menu.
