I have some products with pre defined sequence numbers. I want to write a pattern which will look for sequence numbers Greater than predefined.

For example in the below mentioned code:
$ProdBuild = 'K7000AKNBJQ4333';
My regular expression should match if for any product the last 4 digits are greater than or equal to 4333.

Matching Patterns:
$ProdBuild = 'K7000AKNBKQ4333';
$ProdBuild = 'K7000A-KNBKQ-4333';
$ProdBuild = 'K7000A-KNBKQ-6801';
$ProdBuild = 'K7000TKNBKQ7610';

Non-matching Patterns:
$ProdBuild = 'K7000AKNBKQ4233';
$ProdBuild = 'K7000AKNB4333';
$ProdBuild = 'K7000ANBKQ6845';
$ProdBuild = 'K7000TKNBKQ-1845';
The following code is good except that it can't look for the ones with last 4 digits greater than a specified number. Could some one help me in this part? 
use strict;
use warnings;
no  warnings qw(once);

{
    my $ProdBuild = 'K7000AKNBJQ4333';
    
    if ($ProdBuild =~ m/K7000[A-Z]\-?[A-Z][A-Z][A-Z][A-Z][A-Z]\-?[4-9]
+[3-9]\d+/i) {
        print "Product match $ProdBuild \n"
    }
    else {
        print "No match found \n"
    }
        
}
