Let Q=P+1
If Q is a twin prime number then S is not complete
If Q is composite then some prime factor p divides Q, if this factor p were in our list S then it would divide P, but p divides P+1=Q. If p divides P and Q then p would have to divide the difference of the two numbers which, which is (P+1)P or just 1. Since no twin prime number divides 1, p can not be on the list. This means that at least one twin prime number exists
beyond those in the list.

Q is divisible by two. See my previous post.
Also, p doesn't have to be a twin prime, it can be some other prime, like 2 for example.
