Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491466, here are decompositions:

5 + 33491461 = 33491466
7 + 33491459 = 33491466
79 + 33491387 = 33491466
97 + 33491369 = 33491466
103 + 33491363 = 33491466
163 + 33491303 = 33491466
199 + 33491267 = 33491466
233 + 33491233 = 33491466

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.10.10.

Address: 1.255.10.10
Class: public
IPv4-mapped IPv6: ::ffff:1.255.10.10

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