Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456762, here are decompositions:

23 + 31456739 = 31456762
41 + 31456721 = 31456762
59 + 31456703 = 31456762
83 + 31456679 = 31456762
173 + 31456589 = 31456762
383 + 31456379 = 31456762
401 + 31456361 = 31456762
431 + 31456331 = 31456762

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.223.253.250.

Address: 1.223.253.250
Class: public
IPv4-mapped IPv6: ::ffff:1.223.253.250

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