Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554280, here are decompositions:

7 + 33554273 = 33554280
13 + 33554267 = 33554280
31 + 33554249 = 33554280
41 + 33554239 = 33554280
59 + 33554221 = 33554280
79 + 33554201 = 33554280
113 + 33554167 = 33554280
157 + 33554123 = 33554280

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.255.104.

Address: 1.255.255.104
Class: public
IPv4-mapped IPv6: ::ffff:1.255.255.104

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