Make-believe is an expression of infinity in a sense. Therefore if you start with 1,2,3,... n with n being a prime number it would be sufficient to invent n+1 or n+2 or n+3 (etc.) to find a non prime number. Coming up with a new gender when you reach a prime ultimate number is sufficient to express as non-prime.
