Can i change my iCloud primary email

Can i change my iCloud primary email (note this is not the same as my Apple ID email)

My Apple ID email is name@mydomain.com

My primary iCloud email is incorrectlycreated@icloud.com

The iCloud account seems bound to my Apple ID, how do I change it to the correct email address?

Basically i created the iCloud address incorrectly when i set it up (with an employees name and not my own because i thought I was logged into the computer under his account. now his name is primary email address on iCloud account that is bound to my Apple ID,

I've had my Apple ID for years and my iCloud account was upgraded from MobileMe account at the time.

Help!
