Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489764, here are decompositions:

47 + 2147489717 = 2147489764
113 + 2147489651 = 2147489764
227 + 2147489537 = 2147489764
281 + 2147489483 = 2147489764
467 + 2147489297 = 2147489764
521 + 2147489243 = 2147489764
557 + 2147489207 = 2147489764
677 + 2147489087 = 2147489764

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.23.228.

Address: 128.0.23.228
Class: public
IPv4-mapped IPv6: ::ffff:128.0.23.228
