Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483434, here are decompositions:

5 + 31483429 = 31483434
43 + 31483391 = 31483434
83 + 31483351 = 31483434
107 + 31483327 = 31483434
127 + 31483307 = 31483434
173 + 31483261 = 31483434
197 + 31483237 = 31483434
271 + 31483163 = 31483434

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.102.42.

Address: 1.224.102.42
Class: public
IPv4-mapped IPv6: ::ffff:1.224.102.42

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