Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498020, here are decompositions:

71 + 2147497949 = 2147498020
113 + 2147497907 = 2147498020
131 + 2147497889 = 2147498020
251 + 2147497769 = 2147498020
263 + 2147497757 = 2147498020
359 + 2147497661 = 2147498020
449 + 2147497571 = 2147498020
461 + 2147497559 = 2147498020

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.56.36.

Address: 128.0.56.36
Class: public
IPv4-mapped IPv6: ::ffff:128.0.56.36

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