What does Goldbach's conjecture say about even integers above 2?
AEach is a sum of two primes
BEach is a product of two primes
CEach is a difference of two primes
DEach is a square of a prime
Answer & Solution
Correct answer: A. Each is a sum of two primes
1. Goldbach's conjecture concerns even integers greater than 2.
2. It says each can be expressed as the sum of two primes (for example 10 = 3 + 7).
3. It is an unsolved question, and the product, difference or square wording is not the claim.
