  • Mathematics

Given an integer n, find all prime numbers p between 1 and n where both p and p+2 are prime numbers. These pairs are called twin primes. Return all twin prime pairs in ascending order.

Constraints:

  • 2 ≤ n ≤ 10⁶
  • All prime pairs should be returned in order
  • Each pair should be returned as [p, p+2]

Examples:

Input: n = 10
Output: [[3,5],[5,7]]
Explanation: (3,5) and (5,7) are twin prime pairs
Input: n = 20
Output: [[3,5],[5,7],[11,13],[17,19]]
