```If it can be proved that every two-way sieve of eratosthenes has at least
one hole, the conjecture can be proven.  What this means is that (since oles
are at 2k, 3k, 5k, nmod2+2k, nmod5+5k, etc.)  There has got to be some kind
of proof saying that for any given number n, there is a prime in n than
cannot be expressed by nmodp+pk.  What has to be looked at is the modulo
values that will be given for ns. I think we can often choose 3, because the
only case when 2 can be covered is if we have nmod2=1 and pk=2.  (or if the
number is divisible by 3).  Otherwise we can simply continue moving up our
primes.  In the case of 2n=22, we see holes at 3,5, and 11.  What is needed
to continue is a way to prove there will always be a p that doesn't equal
nmodp +pk
