Ibrahima Sambégou Diallo may have become the first African mathematician of the contemporary era to have elaborated a theorem.  This Guinean journalist who recently reconverted himself into mathematics has found the solution to the Goldbach’s conjecture, which is one of the oldest best unsolved mathematics problems of all times.  The Goldbach’s conjecture was elaborated 270 years ago by Christian Goldbach, tutor of the tsar Peter II, and employee in the Russian Foreign affairs’s ministry.  In 1742, Goldbach sent a letter to Euler, stating the Goldbach’s conjecture: “Every even integer greater than 2 can be expressed as the sum of two primes.” For instance, 6 = 3 + 3; 8 = 3 + 5; 10 = 3 + 7 = 5 + 5; 30 = 11 + 19 = 13 + 17; 100 = 17 + 83 … This mathematical problem was so hard to solve…
