Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492356, here are decompositions:

3 + 2147492353 = 2147492356
17 + 2147492339 = 2147492356
29 + 2147492327 = 2147492356
59 + 2147492297 = 2147492356
173 + 2147492183 = 2147492356
197 + 2147492159 = 2147492356
419 + 2147491937 = 2147492356
599 + 2147491757 = 2147492356

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.34.4.

Address: 128.0.34.4
Class: public
IPv4-mapped IPv6: ::ffff:128.0.34.4

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