Can the sum of 2 odd prime numbers ever be prime?

No. The sum of two odd numbers is always even, and no prime is even (apart from 2, but it is the lowest prime, so no primes can be added to form it).


Is it possible to get a even number as the sum ofm three odd prime numbers?

The sum of three odd numbers will be odd, whether they are prime or not. The sum of three prime numbers can be even as long as one of them is 2.


Are odd numbers cannot be written as sum of prime numbers?

Some odd numbers can be written as the sum of prime numbers. 2 + 3 = 5


What 3 odd prime numbers have sum 32?

That isn't possible. The sum of three odd numbers will always be odd. You can make the sum of 3 prime numbers equal to 32 if one of them is 2 (which is not odd).


What are the numbers as sum of 2 prime numbers?

The sum of two prime numbers greater than 2 is an even number. The sum of 2 and any other prime number is an odd number.


All odd numbers greater than 7 can be expressed as the sum of three prime numbers. Which 3 prime numbers has a sum of 43?

11,13,19


What is the sum of the odd prime numbers from 1-20?

It is 75.


What 2 odd primes equal the sum of 10?

The prime numbers 3 an 7 are both odd and sum to 10.


What are 2 prime numbers whose sum is an odd number?

It could any odd prime number and 2 since 2 is the only even prime number and add whole numbers to an odd sum requires both odd and even.In other words, 2 and any other prime will work.


Do odd numbers cannot be written as sum of prime numbers?

No. 2 + 3 = 5


What 2 odd prime numbers have sum 50?

13 + 37


Is there an even number which can be written as the sum of four odd primes?

Prime numbers can only be odd, otherwise they'd be divisible by two, and thus not prime. But, as an example: 1 x 3 x 5 x 7= 105. (odd) An odd times an odd is always odd. Since primes are by definition odd, one cannot multiply four prime numbers and get anything other than an odd number, as each step produces an odd number. Thus a multiplicative sum of four primes is always odd. If by a sum you actually mean addition, then anytime you add two odd numbeers you get an even number, so any four prime numbers will give you an even result every time, and one answer is above. I assume you are only dealing with real numbers.Another Answer:Except for the number 2, which is even and prime, all prime numbers are odd. The sum of any two odd numbers is even, and the sum of any two even numbers is even, so the sum of any four odd numbers is also even. There are an infinite number of even numbers that can be written as the sum of four odd prime numbers. The first example is 3 + 5 + 7 + 11 which equals 26 or, in the full case, 3 + 3+ 3 + 3 which equals 18.
