The sequence `4813065297` has 5 adjacent pairs in descending order; namely `81`, `30`, `65`, `52`, `97`. I want to highlight these pairs by means of overlines, but the pair `65` overlaps with `52`, so I can only get a continuous overline:

`\[4\overline{81}\overline{30}\overline{652}\overline{97}\]`

**Q:** How can I get an overline from `6` to the middle of `5`, followed by another from there to `2`, with a small visible gap?
