Goldbach's conjecture

Statement

The conjecture has the following equivalent forms:

Every even integer greater than $\text{[math]}$ is expressible as a sum of two (possibly equal) primes.
Every even integer greater than $\text{[math]}$ is expressible as a sum of two (possibly equal) odd primes.

A partition of an even integer as a sum of two primes is termed a Goldbach partition.

Name of conjecture/fact	Statement	Status
Weak Goldbach conjecture	every odd integer greater than $\text{[math]}$ is expressible as the sum of three odd primes	corollary of generalized Riemann hypothesis
Vinogradov's theorem	every sufficiently large odd integer is expressible as the sum of three odd primes. Also finds that there are many such triples. The current bound of sufficiently large is approximately $\text{[math]}$	proved
Haselgrove's strengthening of Vinogradov's theorem	in the statement of Vinogradov's theorem, we can choose the three primes to be roughly equal	proved
Chaohua's strengthening of Vinogradov's theorem	numerically strengthens Haselgrove's statement	proved
Schnirelmann's theorem on Goldbach's conjecture	every even integer greater than $\text{[math]}$ is expressible as the sum of at most $\text{[math]}$ primes	proved
Chen's theorem on Goldbach's conjecture	every sufficiently large even integer is expressible as the sum of a prime number and a semiprime, i.e., a number that is either prime or is a product of two primes	proved
