Hey Shulei,

I am assuming you wanted two prime numbers and with the following conditions:

1. M/2<p1<M
2. 2<p2<M

I suggest you use the primes() function to generate a vector of prime numbers upto M and then you write a simple code to choose your p1 and p2 from the vector according to the conditions.
