This number is a composite.

This number is a titanic PRP (GMPY2, PFGW) prime midpoint (MT) where MT-1 and MT+1 are both prime. It is derived from the midpoint of a pair of larger "Martini" primes from the relationship MT * K = MP where MP is the midpoint between two primes where the prime gap delta is not itself a twin midpoint. For this number K is 21099 and delta is 2352058. [Maughan]
