How many prime numbers are known as of the moment you read this question? Can the number [math]n^4 + 4[/math] be prime if [math]n \gt 1?[/math] Is there a pattern to the prime numbers? Even numbers greater than 3 are always a sum of two prime numbers. How do I prove it? How can I prove that every even number is a sum of two prime numbers? How many primes are there between two numbers? Although it is obvious, is there a mathematical proof that all primes greater than 2 are odd? What is wrong with this prime number identification program? Is it possible to create a mathematical function to obtain the nth prime number? What is the largest known prime number? How many digits does it contain? What is the greatest prime number? Which prime numbers can't be represented as sum of distinct primes other than itself? How is Riemann's hypothesis related to prime numbers and what information it gives about prime numbers? How do you calculate the least prime factor of a number?
