Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33536172, here are decompositions:

11 + 33536161 = 33536172
53 + 33536119 = 33536172
73 + 33536099 = 33536172
101 + 33536071 = 33536172
139 + 33536033 = 33536172
151 + 33536021 = 33536172
179 + 33535993 = 33536172
199 + 33535973 = 33536172

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.184.172.

Address: 1.255.184.172
Class: public
IPv4-mapped IPv6: ::ffff:1.255.184.172

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