LeetCode ProblemPrime Pairs With Target Sum
You are given an integer n. We say that two integers x and y form a prime number pair if: 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. Note: A prime number is a natural number greater than 1 with only two factors, itself and 1.
