Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487100, here are decompositions:

23 + 2147487077 = 2147487100
41 + 2147487059 = 2147487100
71 + 2147487029 = 2147487100
131 + 2147486969 = 2147487100
173 + 2147486927 = 2147487100
191 + 2147486909 = 2147487100
251 + 2147486849 = 2147487100
257 + 2147486843 = 2147487100

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.13.124.

Address: 128.0.13.124
Class: public
IPv4-mapped IPv6: ::ffff:128.0.13.124

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