As promised, I offer here a translation of an article about L. G. Schnirel'mann, written by V. Tikhomirov and V. Uspenskii. It appeared in the Russian magazine Kvant in 1996, No 2. pp. 2-6. The translation took longer than I expected, (for various reasons, mainly laziness), but here it is. The article is ostensibly written for high school students, and in a good year there maybe 5 such students on the planet who would understand and follow most of it. But, it can be read with interested and profit by a typical Ph. D. and there is even a suggestion to a wannabe Ph. D. for a thesis topic. (Removal of the "twice differentiable" hypothesis from one of the Schnirel'mann's theorem) There is a direct connection with this thread in this group as follows: The Schnirel'mann introduced a method which allows one to show that there is a number C with the property that any even number can be written as a sum of at most C primes. Goldbach conjecture states that C = 2. A question was raised as to the value of C that results from the Schnirel'mann's method. A number 300,000 appears in several places, but no one could come up with an exact reference to an honest calculation. The present article perpetuates the myth, in a way, it states that C is of the order of several hundreds of thousands, but no reference is given again.
The article also provides an interesting glimpse into the private lives of Soviet mathematicians: Luzin is alleged to have been a mystic, and Schnirel'mann himself committed suicide at the age of 33 because he expected to be arrested and questioned (tortured?) by NKVD (the precursor of the KGB).
