Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487956, here are decompositions:

127 + 2147487829 = 2147487956
139 + 2147487817 = 2147487956
157 + 2147487799 = 2147487956
199 + 2147487757 = 2147487956
307 + 2147487649 = 2147487956
349 + 2147487607 = 2147487956
547 + 2147487409 = 2147487956
613 + 2147487343 = 2147487956

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.16.212.

Address: 128.0.16.212
Class: public
IPv4-mapped IPv6: ::ffff:128.0.16.212

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