It must have been some real junky concrete if it was 6 and broke
up so bad. I think we can assume it has finished settling. If
the area is not prone to holding lots of water after a rain, I'd
go for it. Rather than sand, I would suggest a compactable select
fill. Here it would be called crusher run or red select. Contact
a local sand and gravel outfit to see what would be normal in your
area. This will still require a thin layer of sand for fine
grading under the pavers.

Let us know how it turns out.
