Copy and Paste in a column in Notepad++

Suppose i have data in notepad++ like this
123
342
456
789
101
102
and i want to edit it by copy data from row 4 to row 6 at one time and paste it in column like this rather than pasting in a single row.
123 789
342 101
456 102
Any help will be grateful Thanku
