We havent seen one decay, yet. However theory says that their half-life is in the 10^31y ballpark
Lets just wait a bit...like 10^20y years.
The Minimal Supersymmetric Standard Model has the most unstable of the possible proton decay chains that hasn't been ruled out by experiment, on the order of 10³⁴ years. But it also has a slew of particles that should have been seen at the LHC already.
If the Universe is destined to expand forever, there is plenty of time for proton decay to occur.
