Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555904, here are decompositions:

3 + 33555901 = 33555904
167 + 33555737 = 33555904
257 + 33555647 = 33555904
293 + 33555611 = 33555904
443 + 33555461 = 33555904
521 + 33555383 = 33555904
563 + 33555341 = 33555904
587 + 33555317 = 33555904

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.5.192.

Address: 2.0.5.192
Class: public
IPv4-mapped IPv6: ::ffff:2.0.5.192

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