J. Kaczorowski et al., A NOTE ON THE EXCEPTIONAL SET FOR GOLDBACHS PROBLEM IN SHORT INTERVALS, Monatshefte fuer Mathematik, 116(3-4), 1993, pp. 275-282
Assume the Generalized Riemann Hypothesis and suppose that H log(-6) x
--> infinity. Then we prove that ail even integers in any interval of
the form (x, x + H) but O(H-1/2 log(3) x) exceptions are a sum of two
primes.
