Schnirelmann Constant
The constant 
in Schnirelmann's theorem such that every integer 
is a sum of at most 
primes. Of course, by Vinogradov's theorem, it is known that 4 primes suffice for all sufficiently large numbers, but this constant gives a sufficient number for all numbers. The best current estimate is 
(Ramaré 1995), and a summary of progress on upper bounds for 
is summarized in the following table.
