Thank you, rogue.
Thank you, bur.
I`ve chosen k=1000039 because it is wellsieved.
For the comparison sieving n=[1..1000000] up to p<1e6:
k=1000039 has 16891 candidates
k=1281979 has 39706 candidates
k=1000039 has only 7 known small primes, it is not Sierpinski number.
Now I have found several less candidates k, but k=1000039 was the first.
I use Sr1sieve & PFGW.
