How many do you want? The first 1,000, first 10,000 and first 1 to 15 million.

Download the list of your choice, reformat it to one/line and a fixed length (9 chars +newline covers the first 15 million), and you can grab as many as you need quickly and cheaply.

my $wanted = 500;
open my $primes, '<', 'primes.txt' or die $!;
my @primes = split "\s+", do{ local $/=\($wanted * 10); <$primes> };
close $primes;
