The Goldbach conjecture for the even numbers from 6 to 1564 [La conjecture de Goldbach pour les entiers pairs de 6 à 1564].

The Goldbach conjecture states that each even integer number N greater or equal to 4 can be written as the sum of two prime numbers. For example:
```                    4   = 2+2
6   = 3+3
8   = 3+5 [= 5+3]
10  = 3+7 = 5+5 [= 7+3]
(...)
70  = 3+67 = 11+59 = 17+53 = 23+47 = 29+41 [= 41+29 = 47+23 = 53+17 = 59+11 = 67+3]

The vertical axis represents the odd numbers P={3, 5, 7, 9,...} starting at 3 (and then includes the prime numbers excluding the first one -2- that is even), when the horizontal axis represents the even numbers N={6, 8, 10, 12,...} starting at 6 (this process does not start at 4=2+2 in order to avoid the first prime number -2 that is an even number- on the vertical axis). Each N-vertical line exhibits the decompositions of N as sums of two prime numbers (N=P1+P2, P1 and P2 having the same color).
