In mathematics, twin primes are defined as two primes that differ from each other by two. Except for the pair, this is the smallest possible difference between two primes. Some examples of twin prime pairs are 3 and 5, 5 and 7, 11 and 13. 11 is the 5th prime  There are no odd numbers between 11 and 13. As a result, they are twin primes. 101 is the 26th prime There are no odd numbers between 101 and 103. As a result, they are twin primes 191 is the 43rd prime The next prime number after 191 is 193. There are no odd numbers between 191 and 193. As a result, they are twin primes. 619 is the 114th prime. The previous prime number before 619 is 617. There are no odd numbers between 617 and 619. As a result, they are twin primes. The string 617 occurs at position 886 of Pi  counting from the first digit after the decimal point. The 3, is not counted.  The string and surrounding digits: 52886587533208381420 617 17766914730359825349 The string after 617 is 1776 The string 1776 oc...
