Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487072, here are decompositions:

11 + 33487061 = 33487072
23 + 33487049 = 33487072
41 + 33487031 = 33487072
131 + 33486941 = 33487072
239 + 33486833 = 33487072
401 + 33486671 = 33487072
431 + 33486641 = 33487072
449 + 33486623 = 33487072

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.248.224.

Address: 1.254.248.224
Class: public
IPv4-mapped IPv6: ::ffff:1.254.248.224

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