It cannot be. If 47 is the sum of two prime numbers, one must be

an even number and one must be an odd number, because that is the

only way to have a sum that is an odd number, such as 47. The only

even prime number is 2. The number that with 2 will have a sum of

47 is 45. However, 45 is not a prime number. Therefore, there are

not two prime numbers that have a sum of 47.
