Prime 997 revisited.

Some trivial contemplation about prime numbers:

Well, I try to be positive more often.

And it's also divisible by 31+6i and by 31-6i. What a complex situation!

Don't forget -31+6i, -31-6i, 6+31i, 6-31i, -6+31i, and -6-31i.

I added proper definitions to the article; all the clever replies are now void :devil:.

Are you going to write an article about number 889 too?

Yes—Ode to 889; [URL="https://www.cynicusrex.com/file/889.html"]https://www.cynicusrex.com/file/889.html[/URL].

[QUOTE]889.

A number that will never be prime.

No matter its yearning for mathematics heaven,

889 will forever be divisible by one hundred twenty-seven.

Composite, not even capable of numbing its woes with wine,

forever living in the shadow of its parents—divine.[/QUOTE]
