For anyone following along at home, you missed a D at the very end (0x6D). A number whose hexadecimal representation ended in 6 couldn't be prime because it is even.

(final digit is divisible by d ←→ number is divisible by d works for any d that is a divisor of the base the number is written in)

Thanks for the edit. Of course an even number isn't prime ;)

There is one even prime. ;-)

And one even primer.

... that ruined it for all the other even numbers :)
