Considering that lists of prime numbers are easily available, I'm not so sure whether a sieve beats reading them from disk.

Unless one is doing it for fun, as an exercise, to check the validity of the list, or to expand a list, there's no reason to write a program that generates prime numbers starting from 2. We promote people to reuse code and not reinvent the wheel. There's no reason to be different when it comes to data.
