Answer»

ANSWER:      

The sum of two odd primes is (5,31),(7, 29),(13, 23),(17,19).

Step-by-step explanation:

Given : Number 36.

To find : Express 36 as the sum of two odd primes.

Solution :

First we write all PRIME numbers between 1 to 36,

Prime numbers -  3, 5, 7, 11, 13, 17, 19 23, 29, 31

Now, TRY to make sum of two prime numbers equal to 36.

36–3=33 not a prime number.

36–5=31 , is a prime number.

So the first pair is (5,31).

36–7=29 , is a prime number.

So the 2ND pair is (7, 29).

36–11=25 not a prime number.

36–13=23 is a prime number.

So the 3rd pair is (13, 23).

36–17=19 ,is prime number.

So the 4th pair is  (17,19).

Therefore, The sum of two odd primes is (5,31),(7, 29),(13, 23),(17,19).
