Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491072, here are decompositions:

3 + 2147491069 = 2147491072
5 + 2147491067 = 2147491072
11 + 2147491061 = 2147491072
29 + 2147491043 = 2147491072
53 + 2147491019 = 2147491072
71 + 2147491001 = 2147491072
149 + 2147490923 = 2147491072
173 + 2147490899 = 2147491072

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.29.0.

Address: 128.0.29.0
Class: public
IPv4-mapped IPv6: ::ffff:128.0.29.0

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