Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487328, here are decompositions:

19 + 33487309 = 33487328
67 + 33487261 = 33487328
109 + 33487219 = 33487328
139 + 33487189 = 33487328
181 + 33487147 = 33487328
211 + 33487117 = 33487328
307 + 33487021 = 33487328
331 + 33486997 = 33487328

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.249.224.

Address: 1.254.249.224
Class: public
IPv4-mapped IPv6: ::ffff:1.254.249.224

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