Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487420, here are decompositions:

11 + 2147487409 = 2147487420
17 + 2147487403 = 2147487420
19 + 2147487401 = 2147487420
47 + 2147487373 = 2147487420
61 + 2147487359 = 2147487420
151 + 2147487269 = 2147487420
173 + 2147487247 = 2147487420
193 + 2147487227 = 2147487420

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.14.188.

Address: 128.0.14.188
Class: public
IPv4-mapped IPv6: ::ffff:128.0.14.188
