PS
Conway's fifth problem is somewhat ambiguous.
I guess the prize is really for a proof that every number reaches a prime,
which of course is still open. But you could interpret the prize as
referring just to the last sentence, which talks about 20 continuing to
more than a hundred digits without reaching a prime and which is
contradicted by A037274!
