Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496492, here are decompositions:

3 + 31496489 = 31496492
43 + 31496449 = 31496492
73 + 31496419 = 31496492
103 + 31496389 = 31496492
163 + 31496329 = 31496492
199 + 31496293 = 31496492
229 + 31496263 = 31496492
271 + 31496221 = 31496492

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.153.44.

Address: 1.224.153.44
Class: public
IPv4-mapped IPv6: ::ffff:1.224.153.44

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