Answer 2

what is odd prime no.?

The odd numbers which are divisible by 1 and itself are called odd prime numbers.

SOLUTION:-

So, the odd prime numbers till 20 are

3 , 5 , 7 , 11 , 13 , 17

Here, 18 is an even number but not aprime number.

Now, we have to check sum of all odd prime numbers sums to 18.

So, 5+ 13 = 18

7+ 11 = 18

Hence, 18 is the sum of two odd primes are $\boxed{\bold{5 + 13}}$ and $\boxed{\bold{7 + 11.}}$
