# 292

This number is a composite.

292! + 291! ± 1 are 595-digit twin primes. [Luhn]

Excluding those assigned only to private boxholders, there are 292 prime Australian postcodes. Not to mention the fact that 292 is the sum of all numbers which can be expressed as the sum of two distinct primes in exactly two ways. [Benney]

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