Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491716, here are decompositions:

17 + 2147491699 = 2147491716
107 + 2147491609 = 2147491716
109 + 2147491607 = 2147491716
113 + 2147491603 = 2147491716
157 + 2147491559 = 2147491716
163 + 2147491553 = 2147491716
173 + 2147491543 = 2147491716
179 + 2147491537 = 2147491716

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.31.132.

Address: 128.0.31.132
Class: public
IPv4-mapped IPv6: ::ffff:128.0.31.132

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