Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486400, here are decompositions:

11 + 33486389 = 33486400
29 + 33486371 = 33486400
47 + 33486353 = 33486400
131 + 33486269 = 33486400
137 + 33486263 = 33486400
149 + 33486251 = 33486400
251 + 33486149 = 33486400
257 + 33486143 = 33486400

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.246.64.

Address: 1.254.246.64
Class: public
IPv4-mapped IPv6: ::ffff:1.254.246.64

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