ISC 2018 Practical: Gold Bach Number Program
A Gold Bach number is a positive even integer that can be expressed as the sum of two odd primes.Note: All even integer numbers greater than 4 are Gold Bach numbers.Example:6 = 3 + 310 = 3 + 710 = 5 + 5Hence, 6 has one odd prime pair 3 and 3. Similarly, 10 has two odd prime pairs, i.e. 3, 7 and 5, 5
