Could you let me know the example of affine scheme which is irreducible but not connected? I know affinescheme SpecA is irreducible only if nillradical of A is prime ideal. But I have trouble with judging whether given scheme is irreducible... I can tell which is integral, connected, reduced, more easily than irreducibility.
