2489

This number is a composite.

+ 2489 = 19*131 and 2483 = 13*191. Note the prime factorizations are anagrams of each other. [Benney]

+ The sum of five consecutive full period primes is the semiprime 2489 whose prime factors are also full period primes. (Proof: 487+491+499+503+509=2489=19*131) [Bowser]
