The question is one which if one thinks about for a small amount of time should be likely to be very difficult. And the OP did not indicate any attempt at thinking about the question. If for example, the OP had mentioned that this is a sparse family of twin primes, or if the OP had indicated they had done some small numerical checking it would likely have been substantially better received. | |
