Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489540, here are decompositions:

3 + 2147489537 = 2147489540
37 + 2147489503 = 2147489540
67 + 2147489473 = 2147489540
103 + 2147489437 = 2147489540
139 + 2147489401 = 2147489540
193 + 2147489347 = 2147489540
241 + 2147489299 = 2147489540
277 + 2147489263 = 2147489540

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.23.4.

Address: 128.0.23.4
Class: public
IPv4-mapped IPv6: ::ffff:128.0.23.4

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