Twin Primes

Twin primes are pairs of primes of the form (p, p + 2). The term “twin prime” was coined by Paul Stckel (1892-1919). The first few twin primes are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43). In this problem you are asked to find out the S-th twin prime pair where S is an integer that will be given in the input. Input The input will contain less than 10001 lines of input. Each line contains an integers S (1 ≤ S ≤ 100000), which is the serial number of a twin prime pair. Input file is terminated by end of file. Output For each line of input you will have to produce one line of output which contains the S-th twin prime pair. The pair is printed in the form (p1,p2). Here means the space character (ASCII 32) . You can safely assume that the primes in the 100000-th twin prime pair are less than 20000000. Sample Input 1 2 3 4 Sample Output (3, 5) (5, 7) (11, 13) (17, 19)
