Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500880, here are decompositions:

67 + 2147500813 = 2147500880
157 + 2147500723 = 2147500880
373 + 2147500507 = 2147500880
541 + 2147500339 = 2147500880
757 + 2147500123 = 2147500880
769 + 2147500111 = 2147500880
787 + 2147500093 = 2147500880
883 + 2147499997 = 2147500880

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.67.80.

Address: 128.0.67.80
Class: public
IPv4-mapped IPv6: ::ffff:128.0.67.80

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