Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487894, here are decompositions:

17 + 33487877 = 33487894
47 + 33487847 = 33487894
137 + 33487757 = 33487894
263 + 33487631 = 33487894
383 + 33487511 = 33487894
443 + 33487451 = 33487894
593 + 33487301 = 33487894
617 + 33487277 = 33487894

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.252.22.

Address: 1.254.252.22
Class: public
IPv4-mapped IPv6: ::ffff:1.254.252.22

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