This code works by concatenating some random numbers, and then scaling the result to the appropriate size:

use strict;

my $max = 3020300000;

for ( 1 .. 10 ) {
    my $rnd = "";
    my $div = "1";
    for ( 0 .. length($max)/3 ) {
        $rnd .= sprintf( "%03d", int( rand( 1000 ) ) );
        $div .= "000";
    }
    my $return = int( $max * $rnd / $div );

    print "$return\n";
}
__END__
