Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479420, here are decompositions:

3 + 33479417 = 33479420
43 + 33479377 = 33479420
67 + 33479353 = 33479420
97 + 33479323 = 33479420
103 + 33479317 = 33479420
211 + 33479209 = 33479420
313 + 33479107 = 33479420
409 + 33479011 = 33479420

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.218.252.

Address: 1.254.218.252
Class: public
IPv4-mapped IPv6: ::ffff:1.254.218.252

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