Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487752, here are decompositions:

61 + 2147487691 = 2147487752
103 + 2147487649 = 2147487752
181 + 2147487571 = 2147487752
211 + 2147487541 = 2147487752
349 + 2147487403 = 2147487752
379 + 2147487373 = 2147487752
409 + 2147487343 = 2147487752
1063 + 2147486689 = 2147487752

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.16.8.

Address: 128.0.16.8
Class: public
IPv4-mapped IPv6: ::ffff:128.0.16.8

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