Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33473840, here are decompositions:

19 + 33473821 = 33473840
61 + 33473779 = 33473840
73 + 33473767 = 33473840
157 + 33473683 = 33473840
163 + 33473677 = 33473840
241 + 33473599 = 33473840
373 + 33473467 = 33473840
409 + 33473431 = 33473840

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.197.48.

Address: 1.254.197.48
Class: public
IPv4-mapped IPv6: ::ffff:1.254.197.48

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