There is no pair of prime numbers that sum to 123.
Proof :
Any two odd primes will sum to an even number, thus excluding 123 which is odd.
Since 2 is the only even prime, the only possible solution is 2 + 121 = 123.
But, 121 is not prime because it is 11 x 11.
A similar proof shows that there is no pair of primes whose difference is 123.
There are two primes that multiply to 123 : - 3 and 41.
3 and 41
The prime factorization of 16 is: 2 x 8 2 x 2 x 4 2 x 2 x 2 x 2. There is not a pair of prime numbers that make 16.
2 and 17
Yes, it can. Examples are 2 and 5 to make 10 and 2 and 7 to make 14. If your question was if they could make an even prime number, the answer is no. Two is the only even prime number.
37 and 5
3 and 41
41 x 3
No two prime numbers can make 30.No two prime numbers can make 30.No two prime numbers can make 30.No two prime numbers can make 30.
To calculate manually if any number is a prime number, divide the number by ascending prime numbers until you reach the square root of the number. In this instance: 123/2 = 61.5 123/3 = 41 Therefore, 123 is not a prime number. However, since the first two factors we discovered are both prime - those being 3 and 41, it must not have any other factors.
1 and 123 or 2 and 61.5 or 3 and 41 or 4 and 30.75 etc
123 is a composite number because it is divisible by 3. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1, 2, and 0. 1, 2, and 0 have a different name.
The prime factors are: 2, 5
223 and 2.

The prime factorization of 16 is: 2 x 8 2 x 2 x 4 2 x 2 x 2 x 2. There is not a pair of prime numbers that make 16.

3 and 23 are two prime numbers having a sum of 26.
