1923
This number is a composite.
The smallest odd-emirpimes (after 15) that can be expressed
as the sum of first n odd-emirpimes, i.e., (15 + 39 + 51 +
... + 185 + 187), (case n=15). [Bajpai]
In 1923, English
mathematicians Hardy and Littlewood figured out how you can
estimate how many twin primes there should be. [Veritasium]
