Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488020, here are decompositions:

11 + 2147488009 = 2147488020
19 + 2147488001 = 2147488020
79 + 2147487941 = 2147488020
89 + 2147487931 = 2147488020
113 + 2147487907 = 2147488020
149 + 2147487871 = 2147488020
151 + 2147487869 = 2147488020
191 + 2147487829 = 2147488020

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.17.20.

Address: 128.0.17.20
Class: public
IPv4-mapped IPv6: ::ffff:128.0.17.20

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