Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474760, here are decompositions:

13 + 31474747 = 31474760
67 + 31474693 = 31474760
73 + 31474687 = 31474760
211 + 31474549 = 31474760
241 + 31474519 = 31474760
271 + 31474489 = 31474760
337 + 31474423 = 31474760
397 + 31474363 = 31474760

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.68.72.

Address: 1.224.68.72
Class: public
IPv4-mapped IPv6: ::ffff:1.224.68.72

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