Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33496720, here are decompositions:

53 + 33496667 = 33496720
71 + 33496649 = 33496720
293 + 33496427 = 33496720
353 + 33496367 = 33496720
359 + 33496361 = 33496720
449 + 33496271 = 33496720
479 + 33496241 = 33496720
503 + 33496217 = 33496720

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.30.144.

Address: 1.255.30.144
Class: public
IPv4-mapped IPv6: ::ffff:1.255.30.144

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