Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489312, here are decompositions:

13 + 2147489299 = 2147489312
109 + 2147489203 = 2147489312
223 + 2147489089 = 2147489312
229 + 2147489083 = 2147489312
571 + 2147488741 = 2147489312
733 + 2147488579 = 2147489312
739 + 2147488573 = 2147489312
769 + 2147488543 = 2147489312

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.22.32.

Address: 128.0.22.32
Class: public
IPv4-mapped IPv6: ::ffff:128.0.22.32
