A Goldbach number is a positive integer that is the sum of two odd primes (Li 1999). Let (the "exceptional set of Goldbach numbers") denote the number of even numbers not exceeding which cannot be written as a sum of two odd primes. Then the Goldbach conjecture is equivalent to proving that for every . Li (1999) proved that for sufficiently large ,
