Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497462, here are decompositions:

13 + 31497449 = 31497462
19 + 31497443 = 31497462
53 + 31497409 = 31497462
71 + 31497391 = 31497462
103 + 31497359 = 31497462
109 + 31497353 = 31497462
149 + 31497313 = 31497462
163 + 31497299 = 31497462

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.156.246.

Address: 1.224.156.246
Class: public
IPv4-mapped IPv6: ::ffff:1.224.156.246

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