Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33624440, here are decompositions:

19 + 33624421 = 33624440
67 + 33624373 = 33624440
97 + 33624343 = 33624440
307 + 33624133 = 33624440
337 + 33624103 = 33624440
379 + 33624061 = 33624440
541 + 33623899 = 33624440
601 + 33623839 = 33624440

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.1.17.120.

Address: 2.1.17.120
Class: public
IPv4-mapped IPv6: ::ffff:2.1.17.120

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