Hey there! That's a great question! Splitting up the accounts will involve what's called a "Change of Responsibility". You will need to initiate a brand new account and request that the 2 lines that you are wishing to separate be moved over.
Please bear in mind, that you will have to sign new EIP agreements if you are making payments on the devices associated with the lines of service to be moved, and if you are on a JUMP! On Demand lease, the payments will not be able to be moved at all, and will have to remain on the original account.
