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

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.
