János Pintz: On the Linnik-Goldbach problem III (joint work with Imre Ruzsa)

Abstract:

   Linnik raised the question whether one can write every sufficiently
   large even integer as the sum of two primes and a bounded number of
   powers of two. He showed this in the 1950s with K powers of two, where
   K was  an unspecified large absolute constant. I will sketch the proof
   that K=8 powers of two suffices, a result announced many years ago and
   worked out recently in details.
