A prime gap is the difference between two successive prime numbers. The n-th prime gap, denoted g(n) is the difference between the (n+1)-th and the n-th prime numbers, i.e. g(n) = p(n+1) - p(n) The first 7 prime numbers are 2, 3, 5, 7, 11, 13, 17, and the first 6 prime gaps are 1, 2, 2, 4, 2, 4. Shinya Yukimura is interested in prime gaps and he need some experimental data to verify his hypothesis. More specifically, given a closed interval [a,b], Shinya wants to find the two adjacent primes p1 and p2 (a
