Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487040, here are decompositions:

11 + 2147487029 = 2147487040
59 + 2147486981 = 2147487040
71 + 2147486969 = 2147487040
113 + 2147486927 = 2147487040
131 + 2147486909 = 2147487040
191 + 2147486849 = 2147487040
197 + 2147486843 = 2147487040
509 + 2147486531 = 2147487040

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.13.64.

Address: 128.0.13.64
Class: public
IPv4-mapped IPv6: ::ffff:128.0.13.64

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