Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488948, here are decompositions:

29 + 2147488919 = 2147488948
41 + 2147488907 = 2147488948
89 + 2147488859 = 2147488948
197 + 2147488751 = 2147488948
257 + 2147488691 = 2147488948
389 + 2147488559 = 2147488948
431 + 2147488517 = 2147488948
641 + 2147488307 = 2147488948

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.20.180.

Address: 128.0.20.180
Class: public
IPv4-mapped IPv6: ::ffff:128.0.20.180

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