Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480042, here are decompositions:

23 + 31480019 = 31480042
239 + 31479803 = 31480042
449 + 31479593 = 31480042
491 + 31479551 = 31480042
743 + 31479299 = 31480042
773 + 31479269 = 31480042
911 + 31479131 = 31480042
941 + 31479101 = 31480042

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.88.234.

Address: 1.224.88.234
Class: public
IPv4-mapped IPv6: ::ffff:1.224.88.234

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