First, thanks to answer! And it is much clear to me what I ask .
So I now see sieving is not good idea. Can somebody write a script ( as mentioned before) that will produce primes with such properties.
As I say before, I know it is not perfect, it will not remove all candidates, it cannot be called sieve program. If it is not too complicated to write that script then I would lile to have it, so I can start some home experiment!
LaurV thanks one more time
