Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487076, here are decompositions:

17 + 2147487059 = 2147487076
47 + 2147487029 = 2147487076
107 + 2147486969 = 2147487076
149 + 2147486927 = 2147487076
167 + 2147486909 = 2147487076
197 + 2147486879 = 2147487076
227 + 2147486849 = 2147487076
233 + 2147486843 = 2147487076

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.13.100.

Address: 128.0.13.100
Class: public
IPv4-mapped IPv6: ::ffff:128.0.13.100

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