Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609672, here are decompositions:

23 + 33609649 = 33609672
79 + 33609593 = 33609672
101 + 33609571 = 33609672
139 + 33609533 = 33609672
191 + 33609481 = 33609672
193 + 33609479 = 33609672
251 + 33609421 = 33609672
269 + 33609403 = 33609672

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.215.200.

Address: 2.0.215.200
Class: public
IPv4-mapped IPv6: ::ffff:2.0.215.200

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