Not trying to be a jerk, but why is that interesting? Am I missing something more than all odd numbers end in 1, and primes by their nature cannot be even(except 2, as you mentioned).

Just nitpick but all odd numbers end in an odd number, not 1, and all even numbers end in an even number i.e. a multiple of 2.
Sure, but OP was talking about binary representation.
GP's statement is true for all number systems with an even base (so also for binary and decimal)
All odd numbers end in 1 in binary.
