Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487438, here are decompositions:

29 + 2147487409 = 2147487438
37 + 2147487401 = 2147487438
79 + 2147487359 = 2147487438
137 + 2147487301 = 2147487438
179 + 2147487259 = 2147487438
191 + 2147487247 = 2147487438
211 + 2147487227 = 2147487438
251 + 2147487187 = 2147487438

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.14.206.

Address: 128.0.14.206
Class: public
IPv4-mapped IPv6: ::ffff:128.0.14.206
