Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490880, here are decompositions:

47 + 2147490833 = 2147490880
83 + 2147490797 = 2147490880
107 + 2147490773 = 2147490880
149 + 2147490731 = 2147490880
191 + 2147490689 = 2147490880
467 + 2147490413 = 2147490880
617 + 2147490263 = 2147490880
641 + 2147490239 = 2147490880

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.28.64.

Address: 128.0.28.64
Class: public
IPv4-mapped IPv6: ::ffff:128.0.28.64

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