Goldbach’s Conjecture
A conjecture in mathematics is a claim that appears to be true on paper but has never been demonstrated to be true or false. Russian mathematician Christian Goldbach put up the Golbach's conjecture in 1742, but it has never been proved.
Every even integer higher than two, according to this statement, can be written as the sum of two prime numbers. It seems straightforward enough, but mathematicians need a working proof that demonstrates beyond a shadow of a doubt that it is true in order to demonstrate it.
For numbers up to 100,000, a mathematician proved the conjecture in 1938. Later, a computer program verified it for greater numbers as well, although that doesn't offer a comprehensive proof. Despite the fact that numerous mathematicians have attempted to answer it since it was first proposed, it continues to be one of the oldest unsolved math problems in history.
