he Goldbach's weak conjecture states that every odd number greater than 7 can be expressed as the sum of three odd primes. Liu Ming-Chit and Wang Tian-Ze proved that for numbers greater than 2·101346 Goldbach's weak conjencture is true, so checking every number under this figure is perfect for using Distributing Computing architecture like BOINC. And this would make the weak Goldbach conjecture effectively proved.
