Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147540066, here are decompositions:

3 + 2147540063 = 2147540066
43 + 2147540023 = 2147540066
193 + 2147539873 = 2147540066
229 + 2147539837 = 2147540066
277 + 2147539789 = 2147540066
313 + 2147539753 = 2147540066
379 + 2147539687 = 2147540066
487 + 2147539579 = 2147540066

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.220.98.

Address: 128.0.220.98
Class: public
IPv4-mapped IPv6: ::ffff:128.0.220.98

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