Harvest: The first thought is 1 million of all the numbers, the title requirement is as long as even, can also be analyzed out, if it is given an odd number, when we give him greater than or equal to 3 odd (this count plus may not be prime, but at least meet is odd, as for is not prime number also to judge), cut out must be an even In any case, the answer is not given, but the title requires an even number,

Approximate test instructions: given [l,r] interval, find each prime in the intervalData range:1R-l 1,000,000.R value is too large, so can not directly sieve [0,r], to space and time optimization, using the interval sieve method, but also note that can not use int, because R and L are full int, the middle has a lot of detail processing will explode int, also note that 1 is not prime, so in the interval siev
