    From the press release:
    :oldsmile:

    Anyway, when I was born the largest known prime had 687 digits. Now standing at 22,338,618. Amazing number!

    This is an interesting inverse problem. Fortunately, it is well-posed. :smile:

    I'm sure there's another one even larger just around the corner.

    Imagine how many we'd have if they were tied to winning the powerball lottery.

    The news has reached the Belgian press via our main news agency Belga: http://www.nieuwsblad.be/cnt/dmf20160120_02079664

    The last sentence says (translated): "It is not known how many prime numbers there are." :headbang:

    Shouldn't someone write to them about that?

    I sent them an email (that's the functionality they have to suggest corrections).
