Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489154, here are decompositions:

11 + 2147489143 = 2147489154
67 + 2147489087 = 2147489154
71 + 2147489083 = 2147489154
131 + 2147489023 = 2147489154
137 + 2147489017 = 2147489154
157 + 2147488997 = 2147489154
241 + 2147488913 = 2147489154
463 + 2147488691 = 2147489154

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.21.130.

Address: 128.0.21.130
Class: public
IPv4-mapped IPv6: ::ffff:128.0.21.130

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