Description: Odd integers greater than ( ; 1 0 ^ ; 2 7 ) have at least a representation as a sum of three odd primes. Final statement in section 7.4 of Helfgott p. 70 , expressed using the set G of odd numbers which can be written as a sum of three odd primes. (Contributed by Thierry Arnoux, 22-Dec-2021)
