They are: 5+7+11 = 23

For two numbers to equal an odd number, you need one to be even and the other odd. In this case, we want both to be prime. The only even prime number is 2. Therefore, the other number must be 23. This is prime, and so yes, 2 prime numbers can equal 25, however 2 and 23 are the only possible pair.
