Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557928, here are decompositions:

7 + 33557921 = 33557928
11 + 33557917 = 33557928
17 + 33557911 = 33557928
29 + 33557899 = 33557928
37 + 33557891 = 33557928
101 + 33557827 = 33557928
139 + 33557789 = 33557928
179 + 33557749 = 33557928

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.13.168.

Address: 2.0.13.168
Class: public
IPv4-mapped IPv6: ::ffff:2.0.13.168

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