Something wrong?A Prussian mathematician whose friendly letter to Leonhard Euler in 1742 posed a question about even numbers and primes that remains unproven nearly three centuries later - one of the oldest open problems in mathematics.

About this person
Christian Goldbach was born 18 March 1690 in Prussia, studied law, and spent his early years traveling Europe before landing in Russia in 1725 as a professor at the newly founded Saint Petersburg Academy of Sciences. He jointly led the academy in 1737, but stepped away from academic duties in 1742 to work in the Russian Ministry of Foreign Affairs, where he remained until his death on 20 November 1764. His close friendship with Leonhard Euler sparked mathematical exchanges that inspired some of Euler's own work. Today he's remembered for two legacies: the Goldbach-Euler theorem and the conjecture that bears his name alone - a deceptively simple claim about numbers that no one has managed to prove or break.
