Product of Two Prime Numbers

Write a function that returns True if the given number num is a product of any two prime numbers.

Examples

product_of_primes(2059) ➞ True
# 29*71=2059

product_of_primes(10) ➞ True
# 2*5=10

product_of_primes(25) ➞ True
# 5*5=25

product_of_primes(999) ➞ False
# There are no prime numbers.

• num is always greater than 0.
• 0 and 1 aren't prime numbers.
