I noticed some inconsistencies in your requirement!

If you want to split each alpha-numeric string greater than 3 character length, then why the following highlighted 4 character length string is not considered?
Code:
21 435g asd 3dd jklfjwe wer

By the way if your requirement is to split strings that are greater than 4 character length, then try this code:
Code:
awk '
        {
                for ( i = 1; i <= NF; i++ )
                {
                        if ( length ($i) > 4 )
                        {
                                if ( $i ~ /[a-zA-Z]/ && $i ~ /[0-9]/ )
                                {
                                        gsub( /.../, "& ", $i )
                                        sub(" $", X, $i )
                                }
                        }
                }
        }
