Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484444, here are decompositions:

5 + 2147484439 = 2147484444
11 + 2147484433 = 2147484444
67 + 2147484377 = 2147484444
107 + 2147484337 = 2147484444
113 + 2147484331 = 2147484444
167 + 2147484277 = 2147484444
173 + 2147484271 = 2147484444
211 + 2147484233 = 2147484444

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.3.28.

Address: 128.0.3.28
Class: public
IPv4-mapped IPv6: ::ffff:128.0.3.28

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