Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542920, here are decompositions:

17 + 33542903 = 33542920
53 + 33542867 = 33542920
137 + 33542783 = 33542920
167 + 33542753 = 33542920
197 + 33542723 = 33542920
317 + 33542603 = 33542920
347 + 33542573 = 33542920
353 + 33542567 = 33542920

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.211.8.

Address: 1.255.211.8
Class: public
IPv4-mapped IPv6: ::ffff:1.255.211.8

Public, routable address (assignable to a host on the internet).
