Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520420, here are decompositions:

23 + 33520397 = 33520420
47 + 33520373 = 33520420
53 + 33520367 = 33520420
137 + 33520283 = 33520420
149 + 33520271 = 33520420
179 + 33520241 = 33520420
239 + 33520181 = 33520420
251 + 33520169 = 33520420

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.123.36.

Address: 1.255.123.36
Class: public
IPv4-mapped IPv6: ::ffff:1.255.123.36

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