Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469924, here are decompositions:

67 + 31469857 = 31469924
127 + 31469797 = 31469924
163 + 31469761 = 31469924
193 + 31469731 = 31469924
271 + 31469653 = 31469924
337 + 31469587 = 31469924
397 + 31469527 = 31469924
457 + 31469467 = 31469924

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.49.100.

Address: 1.224.49.100
Class: public
IPv4-mapped IPv6: ::ffff:1.224.49.100

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