How do you test if a Number is Prime?
There is no easy test. You need to divide the number by all the primes up to the square root of the number, so if you want to know if 56789 is prime, you need to divide by all the prime numbers up to 239. If you go through all the primes up to the square root and don't get an even number as the result of the division then the number is prime. (Incidentally, the factors of 56789 are 109 and 521.)
Does the sum of two prime numbers equal a prime number?
If one of the two numbers is 2, the sum of two prime numbers may sometimes be a prime number. Examples of this are 2 + 11 = 13, 2 + 521 = 523, 2 + 281 = 283. There are an infinite number of similar examples where the sum of 2 plus a prime is another prime. However if neither number is 2, then the sum of two prime numbers is always an even number greater than 2 and therefore composite.
