Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505556, here are decompositions:

13 + 33505543 = 33505556
37 + 33505519 = 33505556
109 + 33505447 = 33505556
163 + 33505393 = 33505556
193 + 33505363 = 33505556
379 + 33505177 = 33505556
433 + 33505123 = 33505556
439 + 33505117 = 33505556

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.65.20.

Address: 1.255.65.20
Class: public
IPv4-mapped IPv6: ::ffff:1.255.65.20

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