Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500668, here are decompositions:

7 + 2147500661 = 2147500668
41 + 2147500627 = 2147500668
107 + 2147500561 = 2147500668
109 + 2147500559 = 2147500668
307 + 2147500361 = 2147500668
317 + 2147500351 = 2147500668
367 + 2147500301 = 2147500668
409 + 2147500259 = 2147500668

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.66.124.

Address: 128.0.66.124
Class: public
IPv4-mapped IPv6: ::ffff:128.0.66.124

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