Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557520, here are decompositions:

11 + 33557509 = 33557520
53 + 33557467 = 33557520
67 + 33557453 = 33557520
97 + 33557423 = 33557520
103 + 33557417 = 33557520
107 + 33557413 = 33557520
109 + 33557411 = 33557520
163 + 33557357 = 33557520

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.12.16.

Address: 2.0.12.16
Class: public
IPv4-mapped IPv6: ::ffff:2.0.12.16

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