the best approach to solve this is find out the combinition that will make 23 e.g.
1+22, 2+21, 3+20,4+19, 5+18, 6+17, 7+16, 8+15, 9+14,10+13, 11+12. Then it repeats. Now lets evaluate which pair is prime. (Prime is a number which is divisible by 1 and by itself). SO there is notwoprime numbers which will add up to make a sum of 23.
