哥德巴赫猜想
Galois, who previously gained press attention for allegedly proving Goldbach's conjecture, confesses that he lied to win back Oliva; the publicized sabotage of his presentation was staged to hide his failure. Hilbert reveals that he is the mastermind, that he has spent his entire professional life trying to prove Goldbach's conjecture and was insanely jealous that Galois beat him to the proof; he staged this "convention" to avenge himself. Fermat was a diversion who will be killed when undetectable poison gas is released in his car. Hilbert announces that he's succeeded in proving Goldbach. He hands a folder to Galois. Galois admits that Hilbert's proof is brilliant. Frustrated by their impending doom, Galois becomes angry and strikes Hilbert, rendering him unconscious.
