It's not possible. For two numbers to have a sum of 13, one would have to be even, that is, divisible by 2.
There are 14 even numbers between 12 and 40. To calculate this, you can use the formula for finding the number of integers in a range: (largest number - smallest number) / 2 + 1. In this case, (40 - 12) / 2 + 1 = 28 / 2 + 1 = 14. So, there are 14 even numbers between 12 and 40.
14 is immediately between the whole numbers of 13 and 15.
