WebJul 17, 2016 · Two basic approaches come to mind: 1) pick a random number, test whether it's prime, and repeat the process if it is; 2) find all the prime numbers in the given range, remove them, and pick one of the remaining numbers at random. Which approach is faster depends on the range and how many times you'll be repeating this process.
