Default Prime to get us started...

It's not quite top-5000 material but here's the first one to get us started:

745*2^333239-1 is prime (100318 digits)

This is pretty good for this k-value. Even thought it's relatively average weight, up to n=260K, its previous highest prime to date was at n=75771.
