extract any words after the fourth location

[Jarvin99]

Hi all, an example of what I want is below:

original string	what I want
G01S7	7
B32B3	3
B32B2605	2605
F05B2240	2240

I want to extract any numbers/ substrings after the fourth position of the original string. May I know if there is a way to do so? Thank you.

want=substr(have,5);
