Random high 4-digit (or more) integer to keep it out of the reserved 1024 ports. I try to keep in round, like 867000 and not 8675309
If I'm writing software that will be used on random people's PCs or on computers where there might be a wide variety of software running I will take a deliberate step and search on Google for potential conflicts.
Otherwise, the random port number on an isolated single-purpose system such as a Raspberry Pi or Arduino or even an internal web server is probably good enough.

Actually 867000 is out of the valid range of 0 - 65535 :D
Haha! Whoops. Well, shave some digits off those random numbers.
