Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491484, here are decompositions:

7 + 2147491477 = 2147491484
67 + 2147491417 = 2147491484
211 + 2147491273 = 2147491484
223 + 2147491261 = 2147491484
283 + 2147491201 = 2147491484
373 + 2147491111 = 2147491484
487 + 2147490997 = 2147491484
601 + 2147490883 = 2147491484

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.30.156.

Address: 128.0.30.156
Class: public
IPv4-mapped IPv6: ::ffff:128.0.30.156

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