MATLAB: Symbolic computation ERROR

errorrandirandom number generatorsymsymbolicsymbolic variable

p=sym('5744092954902128823202697');
randi([2,p-2])
So I've defined p and tried to compute randi([2,p-2]), Matlab returns: 'Size and range inputs must be numeric.'.
I know it's something to do with the symbolic variable but I do not know why this is happening, nor the solution. Is there a way to do this without converting p to numeric because I don't want to lose precision
THANK YOU!

Rsymproc = feval(symengine, 'random', p-3);
Rsym = @() feval(symengine, Rsymproc) + 1;
Now each call to Rsym() will return one random number in the range [2, p-2]
Note: the internal procedure generated for this does not accept array sizes, so to generate multiple values, call Rsym multiple times.
