Easily, act as if you proved it. We are generally very hesistent to do this (with good reason), but sometimes practicality takes over.
For example, we have not proven that are current construction of mathematics contains no contradictions (indeed, we have proved that such a proof is impossible), however, we continue to act as if it does.
We have also not proved that factoring numbers is hard, or that NP/=P, but we still act as if these are true.
