Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487046, here are decompositions:

17 + 2147487029 = 2147487046
137 + 2147486909 = 2147487046
167 + 2147486879 = 2147487046
197 + 2147486849 = 2147487046
227 + 2147486819 = 2147487046
587 + 2147486459 = 2147487046
647 + 2147486399 = 2147487046
659 + 2147486387 = 2147487046

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.13.70.

Address: 128.0.13.70
Class: public
IPv4-mapped IPv6: ::ffff:128.0.13.70

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