Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555072, here are decompositions:

11 + 33555061 = 33555072
53 + 33555019 = 33555072
79 + 33554993 = 33555072
101 + 33554971 = 33555072
113 + 33554959 = 33555072
181 + 33554891 = 33555072
223 + 33554849 = 33555072
233 + 33554839 = 33555072

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.2.128.

Address: 2.0.2.128
Class: public
IPv4-mapped IPv6: ::ffff:2.0.2.128

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