Is it known whether there is a polynomial of degree >= 2 whose asymptotic proportion of primes at integer arguments is the same as for the polynomial P(x) = x ? Also: If negative primes count just as positive primes do, then could using only positive integer arguments give a different result from using only negative integer arguments ? --Dan
