There are no two numbers whose product is 23 and whose sum is 10. 23 is a prime number, and the only numbers whose product is 23 are 23 and 1. A prime number can only be divided by itself and 1.

2 + 3 = 5

17 and 3 are two prime numbers whose sum is 20. Their product is 51.

Becouse every prime number (except 2) is odd, the sum of 2 prime numbers will always be even (and 2 is the only even prime). The exceptions are 11 and 2 for example; 11 = prime, 2 = prime and 13=prime.

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.

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.

The sum of any two prime numbers may or may not be prime. The sum of the two prime numbers 2 and 3 is the prime number 5, and the sum of the two prime numbers 5 and 7 is the composite number 12.

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.

73 and 2

3 and 17

They are 13 and 17

There are no such numbers.

what prime numbers have the sum of 54

The sum of any two prime numbers is not always a composite number. The sum of 2 and 11 is 13, and 13 is a prime number, not a composite number.

none

They can be 31+67 = 98

How about: 37+47 = 84

2 and 467 are two prime numbers whose sum is 469.

It cannot be. If 47 is the sum of two prime numbers, one must be an even number and one must be an odd number, because that is the only way to have a sum that is an odd number, such as 47. The only even prime number is 2. The number that with 2 will have a sum of 47 is 45. However, 45 is not a prime number. Therefore, there are not two prime numbers that have a sum of 47.

The sum of two prime numbers will be composite unless one of the prime numbers is 2.

2, 7, and 89 are three prime numbers whose sum is 98.

2 composite numbers whose prime factorization have a sum of 10 are 30 (2+3+5=10) and 21 (3+7=10).

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.

17 is the only prime number that is the sum of four consecutive prime numbers. 2 + 3 + 5 + 7 = 17

The sum of any pair of prime numbers greater than 2 is an even number.
