To welcome the New Year, we're going to celebrate the number 2019. Here's one numerical factoid readers may find charming:
2019 is the smallest number that can be written in 6 ways as the sum of the squares of 3 primes:
7^2 + 11^2 + 43^2 = 2019
7^2 + 17^2 + 41^2 = 2019
13^2 + 13^2 + 41^2 = 2019
11^2 + 23^2 + 37^2 = 2019
17^2 + 19^2 + 37^2 = 2019
23^2 + 23^2 + 31^2 = 2019
