I have issued a contract, but it doesn't contain subtract totalsupply logic, I want to modify the original contract, how can I do that with same contract address?

Does some one know? Please help. Thanks a lot.

No that is not possible. Contract once deployed cannot be modified. You need to deploy new contract again.
