Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490068, here are decompositions:

7 + 2147490061 = 2147490068
127 + 2147489941 = 2147490068
151 + 2147489917 = 2147490068
271 + 2147489797 = 2147490068
631 + 2147489437 = 2147490068
769 + 2147489299 = 2147490068
991 + 2147489077 = 2147490068
1009 + 2147489059 = 2147490068

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.25.20.

Address: 128.0.25.20
Class: public
IPv4-mapped IPv6: ::ffff:128.0.25.20

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