Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520450, here are decompositions:

11 + 33520439 = 33520450
53 + 33520397 = 33520450
83 + 33520367 = 33520450
167 + 33520283 = 33520450
179 + 33520271 = 33520450
269 + 33520181 = 33520450
281 + 33520169 = 33520450
347 + 33520103 = 33520450

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.123.66.

Address: 1.255.123.66
Class: public
IPv4-mapped IPv6: ::ffff:1.255.123.66

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