A prime gap is the difference between two successive prime numbers. For example, if \\( p_n \\) is the \\( n \\)-th prime number, then the prime gap \\( g_n \\) between the \\( n \\)-th and the \\( (n+1) \\)-th prime can be expressed as: \\\[ g_n = p_\{n+1\} - p_n \\\] Prime gaps can vary significantly in size.
