It depends. Given the amounts involved, it is unlikely that ACH was used. With wire transfers, the basic rule is 'once it is out, it is out'. You may be able to get money back by communicating with recipient and by sending a request for the funds back, but they do not have to honor it. Recipient's back will basically ask the recipient if they agree to the return, and if they don't, that is the end of the story. That is basically why CITI was forced to sue. Other recipients played nice. That one recipient did not. edit: There may be some leeway if there is fraud involved, but even then it is more along the lines of bank freezing the funds than about sending them back.
