formatted cell with leading zeros

I have a whole number in cell C2, but i am formatted it in Cell C3 to always have leading zeros combined with the number in Cell C2, where the result will be 8 digits long.

example, my number in cell C2 = 572 but i need it formatted to be 00000572, but if the number was 19 it needs to be formatted to be 00000019 and so on.
