Prime numbers refer to natural numbers containing only two factors (i e  they can only be divided by themselves and 1)  Twin prime numbers refer to two prime numbers with a difference of 2  For example, 3 and 5, 17 and 19  The so-called twin prime number conjecture was put forward by Euclid, a Greek mathematician, which means that there are infinite pairs of twin prime numbers  This topic has not been proved  Recently, the latest research of a Chinese lecturer in the United States shows that, Although it cannot be proved that there are infinite prime pairs with a difference of 2, there are infinite prime pairs with a difference of less than 70 million
The Chinese lecturer has long been engaged in teaching and scientific research in the field of mathematics
 It is believed that if this result is true, it will be a major breakthrough in the development of number theory
