You may find the exact number somewhere else, but a rough approximation is that up to a number "n", about one of every ln(n) numbers is a Prime number. ln() is the natural logarithm (logarithm to the base "e"); in this case, for numbers up to 2 million, you would expect approximate one out of every 14 numbers to be a prime.
