Goldbach Conjecture - Numberphile

TL;DR

Goldbach's Conjecture posits that every even integer is the sum of two prime numbers, a famous unsolved math problem.

Transcript

(Speaking German) That means that a given number is the sum of two primes. I hold it for a completely certain result. Looking aside from the fact that I can't, myself, prove it. So we're talking about Goldbach's Conjecture. One of the real old chestnuts of mathematics. Christian Goldbach was born in 1690 in Königsberg, now part of Russia. And he w... Read More

Questions & Answers

Q: What is Goldbach's Conjecture?

Goldbach's Conjecture states that every even integer greater than 2 can be expressed as the sum of two prime numbers.

Q: Who proposed Goldbach's Conjecture?

Christian Goldbach proposed the conjecture in a letter to Leonard Euler in 1742.

Q: Has Goldbach's Conjecture been proven?

Goldbach's Conjecture remains unproven, despite related conjectures and partial proofs for odd numbers and other prime sums.

Q: Why is proving Goldbach's Conjecture difficult?

Proving Goldbach's Conjecture is challenging due to the vast number of possible ways even integers can be expressed as sums of prime numbers, making it hard to find a unique solution.
