Janos Pintz: On the Linnik-Goldbach problem (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.
