Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487412, here are decompositions:

19 + 33487393 = 33487412
103 + 33487309 = 33487412
139 + 33487273 = 33487412
151 + 33487261 = 33487412
193 + 33487219 = 33487412
223 + 33487189 = 33487412
331 + 33487081 = 33487412
379 + 33487033 = 33487412

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.250.52.

Address: 1.254.250.52
Class: public
IPv4-mapped IPv6: ::ffff:1.254.250.52

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