Ali, Re: the above probability should look like P = 1 - 0.5/Sqrt(2000), which is about 98.5%.

We have a Binomial distribution here. The expectation is evidently n*p = 2000 * 0.5 = 1000 and the probability for getting at least 1000 heads is 0.5. That's also what intuition is telling us... Or do you expect to get with almost certainty (98.5%) at least 10 heads when flipping a coin 20 times?
