Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521828, here are decompositions:

7 + 33521821 = 33521828
31 + 33521797 = 33521828
97 + 33521731 = 33521828
127 + 33521701 = 33521828
139 + 33521689 = 33521828
181 + 33521647 = 33521828
199 + 33521629 = 33521828
367 + 33521461 = 33521828

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.128.164.

Address: 1.255.128.164
Class: public
IPv4-mapped IPv6: ::ffff:1.255.128.164

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