Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491904, here are decompositions:

7 + 2147491897 = 2147491904
67 + 2147491837 = 2147491904
73 + 2147491831 = 2147491904
307 + 2147491597 = 2147491904
331 + 2147491573 = 2147491904
367 + 2147491537 = 2147491904
487 + 2147491417 = 2147491904
631 + 2147491273 = 2147491904

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.32.64.

Address: 128.0.32.64
Class: public
IPv4-mapped IPv6: ::ffff:128.0.32.64

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