Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487236, here are decompositions:

67 + 2147487169 = 2147487236
79 + 2147487157 = 2147487236
379 + 2147486857 = 2147487236
409 + 2147486827 = 2147487236
487 + 2147486749 = 2147487236
547 + 2147486689 = 2147487236
619 + 2147486617 = 2147487236
709 + 2147486527 = 2147487236

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.14.4.

Address: 128.0.14.4
Class: public
IPv4-mapped IPv6: ::ffff:128.0.14.4

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