Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489772, here are decompositions:

59 + 2147489713 = 2147489772
73 + 2147489699 = 2147489772
193 + 2147489579 = 2147489772
229 + 2147489543 = 2147489772
269 + 2147489503 = 2147489772
331 + 2147489441 = 2147489772
349 + 2147489423 = 2147489772
509 + 2147489263 = 2147489772

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.23.236.

Address: 128.0.23.236
Class: public
IPv4-mapped IPv6: ::ffff:128.0.23.236

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