Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488864, here are decompositions:

5 + 2147488859 = 2147488864
71 + 2147488793 = 2147488864
113 + 2147488751 = 2147488864
137 + 2147488727 = 2147488864
173 + 2147488691 = 2147488864
251 + 2147488613 = 2147488864
347 + 2147488517 = 2147488864
557 + 2147488307 = 2147488864

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.20.96.

Address: 128.0.20.96
Class: public
IPv4-mapped IPv6: ::ffff:128.0.20.96
