Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489920, here are decompositions:

3 + 2147489917 = 2147489920
11 + 2147489909 = 2147489920
47 + 2147489873 = 2147489920
71 + 2147489849 = 2147489920
101 + 2147489819 = 2147489920
269 + 2147489651 = 2147489920
281 + 2147489639 = 2147489920
383 + 2147489537 = 2147489920

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.24.128.

Address: 128.0.24.128
Class: public
IPv4-mapped IPv6: ::ffff:128.0.24.128

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