When X and Y are prime numbers X + Y is even unless either X or Y = 2.
(As 2 is the only even Prime number)
Yes for example 5+11 = 16
NO!!!! Other than '2' all prime numbers are odd numbers. 4,6,10 & 20 are all even so they are not prime numbers.
2 + 3 = 5 Two plus any odd prime number is odd.
As all prime numbers greater than zero are odd, p plus 1 would always be even, therefore always be dividable by 2 and therefore not prime
a prime number is a number that you can plus by one
It is: (x+1)(x+4) none of which are prime numbers

A prime plus another prime is at the very least going to be an even number since all primes (with the exception of 2) are odd.
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.
It would always be a natural number.
19 plus 79
They are 23 plus 7 = 30
