Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491330, here are decompositions:

11 + 2147491319 = 2147491330
53 + 2147491277 = 2147491330
107 + 2147491223 = 2147491330
113 + 2147491217 = 2147491330
137 + 2147491193 = 2147491330
191 + 2147491139 = 2147491330
239 + 2147491091 = 2147491330
263 + 2147491067 = 2147491330

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.30.2.

Address: 128.0.30.2
Class: public
IPv4-mapped IPv6: ::ffff:128.0.30.2

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