Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520146, here are decompositions:

17 + 33520129 = 33520146
19 + 33520127 = 33520146
43 + 33520103 = 33520146
59 + 33520087 = 33520146
83 + 33520063 = 33520146
103 + 33520043 = 33520146
167 + 33519979 = 33520146
197 + 33519949 = 33520146

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.122.18.

Address: 1.255.122.18
Class: public
IPv4-mapped IPv6: ::ffff:1.255.122.18

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