Question : Regular Expression to create spacing / new lines

So... I'm in notepad++, I have a text file with a list of filenames:

7-803-1997
46-183-1999
7-159-1985
14-4993-2008
84-1068-2008

I want to run an expression in find/replace that can reformat as follows:

7
803
1997

46
183
1999

and so on... basically breaking it down to three lines per record. Is this possible?
