Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485458, here are decompositions:

7 + 2147485451 = 2147485458
11 + 2147485447 = 2147485458
37 + 2147485421 = 2147485458
47 + 2147485411 = 2147485458
89 + 2147485369 = 2147485458
101 + 2147485357 = 2147485458
149 + 2147485309 = 2147485458
191 + 2147485267 = 2147485458

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.7.18.

Address: 128.0.7.18
Class: public
IPv4-mapped IPv6: ::ffff:128.0.7.18

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