Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475222, here are decompositions:

19 + 2147475203 = 2147475222
29 + 2147475193 = 2147475222
41 + 2147475181 = 2147475222
43 + 2147475179 = 2147475222
73 + 2147475149 = 2147475222
271 + 2147474951 = 2147475222
293 + 2147474929 = 2147475222
331 + 2147474891 = 2147475222

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.223.22.

Address: 127.255.223.22
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.223.22
