For a pair of primes , let Condition be the following:

For all integers , for both and .

Let be the set of all pairs of primes that satisfy Condition . I can show that , so is nonempty. I think it might be true that if and there does not exist a prime such that .

Let . Then I think it may be true that .

Is there an obvious counterexample? (So far, I haven't found any, but I admit I haven't looked terribly hard yet).
