What number is neither prime or the sum of two distinct primes?
One.
Is the sum of two prime numbers always a prime numer?
It is not. Of the infinitely many primes only one (the number 2) is even, the rest are all odd. The sum of any two primes other than 2 is even and therefore not a prime. If one of the primes in the sum is 2 then the sum is a prime only if the other is the lower of a pair of twin primes. So, while it is possible, it is certainly more likely that the sum is a composite.
What 3 prime numbers have the sum of 3?
There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.
There are 25 prime numbers less than 100 is their sum even or odd?
The sum of the 25 primes less than 100 is even (it is 1060).The first prime number is 2. Every other prime number is odd.So, of the 25 primes less than 100, one is even and 24 are odd.Any two odd numbers sum to an even number. Therefore, an even number of odd numbers has an even sum. So the sum of 24 odd numbers is even.Therefore, the sum of the 25 primes less than 100 is even.
What is the smallest possible sum for 4 different prime numbers when the answer is a prime number?
The smallest four prime numbers are 2, 3, 5, 7, and their sum happens to be a prime.
What are the three smallest primes whose sum is a prime number?
3, 5 and 11
What is the smallest sum of 4 prime numbers that is itself a prime number?
The first four primes have this property: 17 = 2 + 3 + 5 + 7 (all primes). So does 23 (2+3+7+11)
Express 46 and 38 as the sum of two odd primes?
To express the numbers 46 and 38 as the sum of two odd primes, you can use the following combinations: For 46: 46 = 43 (a prime number) + 3 (a prime number) 46 = 41 (a prime number) + 5 (a prime number) For 38: 38 = 37 (a prime number) + 1 (a prime number) 38 = 31 (a prime number) + 7 (a prime number) So, 46 can be expressed as the sum of two odd primes in two ways, and 38 can also be expressed as the sum of two odd primes in two ways.
What is the smallest prime number that is a factor of the sum of 32009 and 52009?
The smallest prime number that is a factor of the sum of 32009 and 52009 is: 2
What is the only prime number that is the sum and difference of two primes?
5
What number is neither prime or the sum of two distinct primes?
One.
What is the sum of the smallest prime number?
2
A number that is neither prime nor the sum of 2 distinct primes?
One

There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.
What is the smallest prime number dividing the sum 316 513?
316 + 513 = 829 which is a prime. So the smallest prime number dividing it is 829.
What is the sum greatest and smallest prime number between 60 to 100?
158 is the sum of the greatest and smallest prime numbers between 60 and 97.
