Splitting a range of indexes into groups using geometry nodes

I'm trying to split an object into groups / islands based on it's index value.

Example: The line has 25 indexes and I want to split it up into a group / island that includes 5 indexes.

So each group / island will have 5 indexes

Group 1 will include 0,1,2,3,4
Group 2 will include 5,6,7,8,9 


What I tried but my logic isn't correct.

So I assume you want this?

enter image description here

With Modulo 5 > Equal 4 I delete the edges (every 5th one) and so I can make the split to the islands.

enter image description here

The problem with Split Edges seems to be that both sides of the edge are cut, so you get more "cuts" than you actually want.

Hope it helps.
