Hamming numbers, also known as $5$-smooth numbers, are those whose largest prime factor is no greater than $5$. Let's denote $\Omega(a)$ as the total count of prime factors of $a$, considering multiplicity. Similarly, let $s(a)$ represent the sum of the prime factors of $a$, again considering multiplicity.

The first 5 prime numbers that are also Fibonacci numbers are 2, 3, 5, 13, and 89.
Therefore, the sum of these prime Fibonacci numbers is 2 + 3 + 5 + 13 + 89 = 112. | codefeedback | [

Create a function in Python that takes in a positive integer n as input and returns an array of size n, where the elements are in descending order from n to 1. Additionally, each element in the array must be a prime number.
Example:
Input: 5
Output: [5, 3, 2, 2, 2]
Constraints:
