a math challenge that hasn’t been solved for 200 years

(1)Euler inference
(2)The famous mathematician Leonhard Euler published it in 1769
(3)by inference
(4)It was argued that there is no whole number solution that satisfies the above equation
(5)For nearly 200 years, the reasoning has not been proven and no counter examples have been found
(6)With the invention of computers in 1969, mathematicians prove in a simple way that this reasoning is not true
(7)I just put all the cases into college and turned the computer around to find a counter example
(8)As a result, the paper was also very brief. All the proof that was published was that there was a counter example when I turned the computer around;;
(9)Anyway, it might have been a good thing that the counter examples were close enough to find them by turning their computers around in the ’60s
(10)It’s stupid you can’t even solve this problem, human
