I'm looking for a list or lists of sensibly sized proven primes - all

By "sensibly sized" I mean in the range 512-8192 bits. I'm particularly
after Sophie Germain primes right now, but I guess all primes are of
interest.


Having set a computer to the problem of coming up with a Sophie Germain
prime for the E startup protocol (Diffie-Hellman),  I offer you:

    static final BigInteger g = new BigInteger("2");
    static final BigInteger modulus =
        new BigInteger("11973791477546250983817043765044391637751157152328012"
                        + "72278994477192940843207042535379780702841268263028"
                        + "59486033998465467188646855777933154987304015680716"
                        + "74391647223805124273032053960564348124852668624831"
                        + "01273341734490560148744399254916528366159159380290"
                        + "29782321539388697349613396698017627677439533107752"
                        + "978203");

And the proof?


Cheers,

Ben.
