Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484392, here are decompositions:

43 + 2147484349 = 2147484392
61 + 2147484331 = 2147484392
283 + 2147484109 = 2147484392
331 + 2147484061 = 2147484392
349 + 2147484043 = 2147484392
463 + 2147483929 = 2147484392
499 + 2147483893 = 2147484392
523 + 2147483869 = 2147484392

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.2.232.

Address: 128.0.2.232
Class: public
IPv4-mapped IPv6: ::ffff:128.0.2.232

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