Goldberg's conjecture

WebJan 29, 2024 · In the 1970s Goldberg and Seymour independently conjectured that $\chi'(G) \le \max\{\Delta(G)+1, \, \lceil \Gamma(G) \rceil\}$. Over the past four decades this conjecture, a cornerstone in modern edge-coloring, has been a subject of extensive research, and has stimulated a significant body of work. WebDec 10, 2024 · The Goldbach conjecture, for instance, asks whether every even integer greater than 2 is the sum of two primes. Proving the conjecture true or false would be an epochal event in number theory, allowing mathematicians to better understand the distribution of prime numbers.

WebDec 17, 2024 · The conjecture states that every even number greater than 4 can be expressed as the sum of two prime numbers. The function returns a pair that is just slightly off, for example, goldbach (34) returns (5, 31) rather than the correct answer (3, 31). Similarly, goldbach (38) returns (11, 31). Any ideas where I am going wrong here? Goldbach's conjecture is one of the oldest and best-known unsolved problems in number theory and all of mathematics.
