  We measure whether there are numerous pairs of twin primes (hereafter
referred to as twin prime pairs) according to the prime number inferred by
sieve of Eratosthenes. In this study, we reveal at least three additional twin
prime pairs increased as n is increased by 1, while setting (6n+5)**2 as the
range for estimating twin prime pairs. As a result, we prove the Twin Prime
Conjecture proposed by de Polignac in 1849. That is, there are numerous twin
prime pairs, indicating that there are numerous prime number p for each natural
number k by making p + 2k as prime number for the case of k = 1.
