RegEx to remove a part of numbers

[rddim]

Hello,
I have many lines like this:

12345 1234567.890 123456.789 1234.567 text

I need to have this:

12345 4567.890 3456.789 1234.567 text

i.e. I need only 4 (four) numbers before the decimal at the 2nd and 3rd column

Try replacing \d+(\d{4}\.\d+) with \1 maybe?
