Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478942, here are decompositions:

53 + 33478889 = 33478942
191 + 33478751 = 33478942
293 + 33478649 = 33478942
359 + 33478583 = 33478942
503 + 33478439 = 33478942
509 + 33478433 = 33478942
521 + 33478421 = 33478942
659 + 33478283 = 33478942

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.217.30.

Address: 1.254.217.30
Class: public
IPv4-mapped IPv6: ::ffff:1.254.217.30

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