Question

Express the given number as the sum of two different primes: $24$

Answer 1

Expressing $24$ as a sum of two different prime numbers

Prime number: A number that has only two factors, $1$ and the number itself.

We need to write all prime numbers between $1\mathrm{and}24$,

Prime numbers- $2,3,5,7,11,13,17,19,23$

Next, we have to make sum of two prime numbers equal to $24$.

$24-2=22$ , not a prime number.

$24-3=21$ not a prime number.

$24-5=19$, is a prime number.

So we can express $24=5+19$ as the sum of two different primes.

Hence, $5\mathrm{and}19$ are two diierent prime numbers whose sum is $24$
