/*DescriptionThe sequence of n ? 1 consecutive composite numbers (positive integers that are not prime and not equal to 1) lying between two successive prime numbers p and p + n is called a prime ga

/*DescriptionFor any even number n greater than or equal to 4, there exists at least one pair of prime numbers p1 and p2 such thatn = p1 + p2This conjecture has not been proved nor refused yet.

DescriptionSome positive integers can be represented by a sum of one or more consecutive prime numbers. How many such representations does a given positive integer have? For example, the integer 5

DescriptionEverybody in the Prime Land is using a prime base number system. In this system, each positive integer x is represented as follows: Let {pi}i=0,1,2,... denote the increasing sequence of

DescriptionIn 1742, Christian Goldbach, a German amateur mathematician, sent a letter to Leonhard Euler in which he made the following conjecture:Every even number greater than 4 can be writte
