How can we give /run/beamOn for more than E10

i want to run my code for more than E9 particles but geant4 is taking /run/beamOn for more than E9. can anyone tell me how can i resolve this problem.

make it 5 runs @ 2E9 particles each for 1E10 in total (or whatever number you wish) and accumulate results afterwards

can you please tell me this with an examples? I dont know how to do it with commands.

This should answer your question and point out that you need to be cautious about how your random seed is set.
