Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33500420, here are decompositions:

3 + 33500417 = 33500420
97 + 33500323 = 33500420
103 + 33500317 = 33500420
157 + 33500263 = 33500420
199 + 33500221 = 33500420
211 + 33500209 = 33500420
313 + 33500107 = 33500420
337 + 33500083 = 33500420

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.45.4.

Address: 1.255.45.4
Class: public
IPv4-mapped IPv6: ::ffff:1.255.45.4

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