Default Prime 997 revisited.

Some trivial contemplation about prime numbers:

โ€œPrime 997 revisited. Divisible only by itself and one. Remarkably simple, but simply amazing.โ€ โ€”https://www.cynicusrex.com/file/997.html.

Also divisible by -1 and -997.

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 .

Yesโ€”Ode to 889; https://www.cynicusrex.com/file/889.html.

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 parentsโ€”divine.

If positive, flapping your tongue like that certainly isn't going to help contain the virus.
