Where $data contains data formatted like your example above, use:
$data =~ s/([0-9])(-[0-9])/$1 $2/g;
- 's///' is the search and replace operator.
- '$1' is replaced by what is matched in '([0-9])'
- '$2' is replaced by what is matched in '(-[0-9])'
- the trailing 'g' causes the search and replace to be global.
