So you want to collect those small primes? You could do a list of the Sierpinski (Proth) side of primes like I do for the Riesel side.
I got thousands of them listed!

Even though this is obvious sarcasm, sure thing: You take k * b^n  1, and I'll take k * b^n + 1. Hey: We might just bump into a twin prime pair!
I just have a few searches to finish. (A 40kdigit search, and a 14640digit search.)
More submissions: 1036 * 12
^{5012} + 1 (5412 digits)
770 * 12
^{5002} + 1 (5401 digits)
