Question

Write $67$ as the sum of three prime numbers.

Answer 1

Prime numbers are natural numbers that are divisible by only $1$ and the number itself.

Prime numbers upto $67$ are $2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,57,59,61$

$67$ as a sum of three primes can be written as $13+17+37$.

Hence, $13,17\mathrm{and}37$ are three odd prime numbers whose sum is $67$.
