Make a conjecture about the sum of primes based on the following pattern: 4 = 2 + 2
6 = 3 + 3
8 = 3 + 5
10 = 3 + 7
12 = 5 + 7
and so on.
The sum of primes is equal to an even number.
The sum of primes is equal to the multiple of the primes.
The sum of primes is equal to primes.
The sum of primes is between 4 and 12.
