Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484972, here are decompositions:

11 + 2147484961 = 2147484972
23 + 2147484949 = 2147484972
43 + 2147484929 = 2147484972
53 + 2147484919 = 2147484972
103 + 2147484869 = 2147484972
151 + 2147484821 = 2147484972
181 + 2147484791 = 2147484972
239 + 2147484733 = 2147484972

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.5.44.

Address: 128.0.5.44
Class: public
IPv4-mapped IPv6: ::ffff:128.0.5.44

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