Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33604428, here are decompositions:

17 + 33604411 = 33604428
19 + 33604409 = 33604428
37 + 33604391 = 33604428
107 + 33604321 = 33604428
139 + 33604289 = 33604428
167 + 33604261 = 33604428
181 + 33604247 = 33604428
197 + 33604231 = 33604428

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.195.76.

Address: 2.0.195.76
Class: public
IPv4-mapped IPv6: ::ffff:2.0.195.76

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