What airspeed is required at sea level to create the same aerodynamic pressure as cruise altitude?

I would like to know what speed would be required, at sea level, to exert the same aerodynamic pressure as experienced at cruise altitude.

For example, if an airliner were traveling at 500kn at 35,000' what speed would you travel at sea level to experience the same forces on the air frame?

$$\text{EAS} = \text{TAS} \times \sqrt{\frac{\text{density at altitude}}{\text{density at standard sea level}}}$$
