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

productOfPrimes(2059) ➞ true
// 29*71=2059

productOfPrimes(10) ➞ true
// 2*5=10

productOfPrimes(25) ➞ true
// 5*5=25

productOfPrimes(999) ➞ false
// There are no prime numbers.

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