Sequence A157037 has the numbers that produce these primes. It is possible for several numbers to produce the same prime. In fact, for each of these primes there is a tree of numbers whose (perhaps multiple) derivatives equal the prime. %C A189441 Every upper twin prime is here because for such p, the derivative of 2(p-2) is p. %H A189441 T.
