How can I execute a command over a distance of more than 100 blocks?

I’m using MC Bedrock (On Windows 10), and I want to execute a command at 5000 ~ 5000 using a command block placed at 0 ~ 0. I know this is not possible (at least not without using some other method than mine) because command blocks have a limit of 100 blocks’ distance in which their command is able to run. I have attempted to circumvent this with a very long loop of /execute commands, like this: /execute @s 100 ~ 100 execute @s 200 ~ 200 execute @s 300 ~ 300 and so on. This has not worked. How can I execute a command over a distance of more than 100 blocks?
