Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489812, here are decompositions:

113 + 2147489699 = 2147489812
173 + 2147489639 = 2147489812
233 + 2147489579 = 2147489812
269 + 2147489543 = 2147489812
389 + 2147489423 = 2147489812
521 + 2147489291 = 2147489812
569 + 2147489243 = 2147489812
953 + 2147488859 = 2147489812

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.24.20.

Address: 128.0.24.20
Class: public
IPv4-mapped IPv6: ::ffff:128.0.24.20

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