Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33579980, here are decompositions:

19 + 33579961 = 33579980
61 + 33579919 = 33579980
73 + 33579907 = 33579980
127 + 33579853 = 33579980
139 + 33579841 = 33579980
157 + 33579823 = 33579980
163 + 33579817 = 33579980
211 + 33579769 = 33579980

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.99.204.

Address: 2.0.99.204
Class: public
IPv4-mapped IPv6: ::ffff:2.0.99.204

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