Remarques

*  Pas de partition possible pour les seuls nombres 4 et 6

*  Partition triviale en un seul terme pour les nombres premiers

 

Hors ces partitions triviales:

*  Premier partition d'un nombre premier pour N = 13 = 11 + 2

*  Première partition double pour N  = 10 = 3 + 7 = 2 + 3 + 5 

*  Première partition triple    pour N  = 16 = 3 + 13 = 5 + 11 = 2 + 3 + 11

*  La quantité de partition en nombres premiers distincts croit rapidement
