WebA more accurate, but less memorable way to see it is: 68.3-95.4-99.7. Therefore, for a normal distribution, 95.4% of your observations lie within two standard deviations of the mean. This leaves 4.6% as the sum of the area under the two tails, or 2.3% or 0.023, which is more in line with what you'd expect with the z-score value provided.
