There are 2 places where you see a neighboring eBGP router's AS number.
- neighbor configuration on the local router
- nlri's sent from the neighbor

It sounds from this new description that you want the CE 65510 to
neighbor with PE 65530,
but updates from PE 65530 will show it's public AS number?

According to BGP specification, the CE should receive nlri's
containing 65530 in the path.
You could configure filtering on the CE router to remove 65530 and
prepend the real AS number.
Does that help?
