Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486346, here are decompositions:

7 + 2147486339 = 2147486346
17 + 2147486329 = 2147486346
29 + 2147486317 = 2147486346
53 + 2147486293 = 2147486346
97 + 2147486249 = 2147486346
149 + 2147486197 = 2147486346
199 + 2147486147 = 2147486346
337 + 2147486009 = 2147486346

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.10.138.

Address: 128.0.10.138
Class: public
IPv4-mapped IPv6: ::ffff:128.0.10.138

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