Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525390, here are decompositions:

11 + 33525379 = 33525390
29 + 33525361 = 33525390
71 + 33525319 = 33525390
79 + 33525311 = 33525390
103 + 33525287 = 33525390
109 + 33525281 = 33525390
163 + 33525227 = 33525390
167 + 33525223 = 33525390

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.142.142.

Address: 1.255.142.142
Class: public
IPv4-mapped IPv6: ::ffff:1.255.142.142

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