Are you sure you know what you're doing?
Those are 22^n+1, which can only ever be prime if n=2^m for some n, namely generalised Fermat numbers.

Apperantely not then... Like I said I used NewPGen to sieve the file:
Code:
k*b^n1 with k fixed
k = 22
b = 22
n from 2 to 1.000.000
Then I fired up LLR.exe (3.7.1)
