CodeChefOpen on judge ↗

Huzaifa and Vedant are childhood friends. It's Huzaifa's 18th birthday and Vedant wants to gift him something very special. Vedant knows that Huzaifa is very fond of prime numbers. Vedant has a number $N$ with him. In order to impress Huzaifa, he decides to represent $N$ as the sum of $k$ prime numbers but this will cost him $k$ units ($k$ is the number of prime numbers used whose sum equals $N$ )
