There is only one Prime number and it is '2' You cannot have any other even prime number
There is only one even prime number: 2. So, representing 20 as a sum of even prime numbers would be 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2.

It is 75.
3 + 17 = 20
They are: 2+7+11 = 20
17 and 3 are two prime numbers whose sum is 20. Their product is 51.
The only even prime number is 2. It happens twice in the prime factorization of 20.
To find the sum of all prime numbers between 20 and 40, we first list out the prime numbers in that range: 23, 29, 31, 37. Then, we simply add them together: 23 + 29 + 31 + 37 = 120. Therefore, the sum of all prime numbers between 20 and 40 is 120.
