Goldbach's Conjecture states that every even integer greater than or equal to 4 can be represented as the sum of two prime numbers. For a given even number $n$, we need to calculate the number of unique pairs $(p_1, p_2)$ such that $p_1 + p_2 = n$ and both $p_1, p_2$ are prime numbers. Algorithmic Strategy The maximum value for $n$ is $2^{15}$ ...
