This logic is backward. If you want empirical evidence you can ask WolframAlpha:

There are 25 primes in [1, 100]. There are 16 in [1001, 1100]. There are 6 in [1000001, 1000100].

I agree with your example, and it's what I said. But you're right, I'm wrong. By my own reasoning, any large odd number is likely to be composite. I must have been tired when I wrote my reply.
