TITBIT001) Some interesting property of 2019.

Happy New Year 2019.  I have not solved a  problem here and I shall be starting shortly.Here I provide some interesting property of 2019.

2019 is the smallest number that can be expressed as sum of 3 squares of prime number in 6 different ways

2019 = $7^2+11^2+43^2$
        = $7^2 + 17^2 + 41^2$
        = $13^2+13^2 + 41^2$
        =  $11^2+23^2+37^2$
        = $17^2 + 19^2 + 37^2$
        = $23^2+23^2+31^2$
