You are given an integer n. We say that two integers x and y form a prime number pair if:

\n\n\n\n

Return the 2D sorted list of prime number pairs [xi, yi]. The list should be sorted in increasing order of xi. If there are no prime number pairs at all, return an empty array.

\n\n

Note: A prime number is a natural number greater than 1 with only two factors, itself and 1.

Example 1:

\n\n
\nInput: n = 10\nOutput: [[3,7],[5,5]]\nExplanation: In this example, there are two prime pairs that satisfy the criteria. \nThese pairs are [3,7] and [5,5], and we return them in the sorted order as described in the problem statement.\n
\n\n

Example 2:

\n\n
\nInput: n = 2\nOutput: []\nExplanation: We can show that there is no prime number pair that gives a sum of 2, so we return an empty array. \n
