Question

Express 36 as the sum of two odd primes? ​

Answer 1

Answer:

36 – 7 = 29 , is a prime number. ... 36 – 17 = 19, is a 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).

We have to write all prime numbers between 1 and 36,

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

Next we have 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 a 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).
