A twin prime is a prime number that is either 2 less or 2 more than another prime number—for example, either member of the twin prime pair 17, 19 or 41, In other words, a twin prime is a prime that has a prime gap of two. Sometimes the term twin prime is used for a pair of twin primes; an alternative name for this is prime twin or prime pair. Twin primes become increasingly rare as one examines larger ranges, in keeping with the general tendency of gaps between adjacent primes to become larger as the numbers themselves get larger. However, it is unknown whether there are infinitely many twin primes the so-called twin prime conjecture or if there is a largest pair. The breakthrough [1] work of Yitang Zhang in , as well as work by James Maynard , Terence Tao and others, has made substantial progress towards proving that there are infinitely many twin primes, but at present this remains unsolved. Usually the pair 2, 3 is not considered to be a pair of twin primes. In , Viggo Brun showed that the sum of reciprocals of the twin primes was convergent. The modern version of Brun's argument can be used to show that the number of twin primes less than N does not exceed.

Write three pairs of twin primes below 20

Twin Prime Numbers are the set of two numbers that have exactly one composite number between them. They can also be defined as the pair of numbers with a difference of 2. The name twin Prime was coined by Stackel in In simple words, we can say that where two numbers have a difference of 2, they are said to be Twin Primes. The word twin prime is also used to describe one of the twin primes i.
