Asked in companies
Given a positive even integer 'K', your task is to find two prime numbers whose sum is equal to 'K'. If there are multiple answers, you may find any.
Example , for K = 4 the pair is ( 2, 2) , For K = 10 the pair is ( 3, 7).
Note :
It is guaranteed that 'K' will always be greater than two.
Problem approach
Sometimes the term twin prime is used for a pair of twin primes; an alternative name for this is prime twin or prime pair. Usually, the pair (2, 3) is not considered to be a pair of twin primes. Since 2 is the only even prime, this pair is the only pair of prime numbers that differ by one; thus twin primes are as closely spaced as possible for any other two primes.
