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.
5
24 = 11 + 13 = 5 + 19
Two, if the order of the primes is ignored.
Three ways. 3 + 37 11 + 29 17 + 23
48 = 7 + 41, 48 = 11 + 37, 48 = 17 + 31, and 48 = 19 + 29
5
24 = 11 + 13 = 5 + 19
Two, if the order of the primes is ignored.
Three ways. 3 + 37 11 + 29 17 + 23
2, 19, 79 2, 31, 67 2, 37, 61
2, 19, 79 2, 31, 67 2, 61, 37
It would be 5 ways
23,3 19,7 13,13
Three ways (I think).
There are many ways to do prime factorisation for 20. It is not prime as it has more than 2 factors. The beginning of the prime factorisation is correct, but it is incomplete. These are two ways to complete it. 20 4x5 2x2x5 or 20 2x10 2x2x5 You have to continue using factorisation on all the numbers until all the numbers are prime. The prime numbers will always be the same if it starts with the same original number.

How about: 17+7 = 24, 19+5 = 24 and 11+13 = 24 as three examples
