Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520128, here are decompositions:

41 + 33520087 = 33520128
67 + 33520061 = 33520128
97 + 33520031 = 33520128
149 + 33519979 = 33520128
179 + 33519949 = 33520128
199 + 33519929 = 33520128
251 + 33519877 = 33520128
337 + 33519791 = 33520128

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.122.0.

Address: 1.255.122.0
Class: public
IPv4-mapped IPv6: ::ffff:1.255.122.0

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