# 3087

This number is a composite.

The sum of the first 40 primes is the product of two prime powers of primes, whose reversal is also the product of two prime powers of primes. Note that 3087 = 3^2 * 7^3 and 3087 reversed is 7803 = 3^3 * 17^2. [Post]

(There is one curio for this number that has not yet been approved by an editor.)
