Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474142, here are decompositions:

13 + 31474129 = 31474142
31 + 31474111 = 31474142
109 + 31474033 = 31474142
151 + 31473991 = 31474142
211 + 31473931 = 31474142
241 + 31473901 = 31474142
331 + 31473811 = 31474142
409 + 31473733 = 31474142

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.65.222.

Address: 1.224.65.222
Class: public
IPv4-mapped IPv6: ::ffff:1.224.65.222

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