Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483864, here are decompositions:

7 + 2147483857 = 2147483864
151 + 2147483713 = 2147483864
277 + 2147483587 = 2147483864
367 + 2147483497 = 2147483864
541 + 2147483323 = 2147483864
727 + 2147483137 = 2147483864
787 + 2147483077 = 2147483864
811 + 2147483053 = 2147483864

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.0.216.

Address: 128.0.0.216
Class: public
IPv4-mapped IPv6: ::ffff:128.0.0.216

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