Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468802, here are decompositions:

103 + 31468699 = 31468802
229 + 31468573 = 31468802
331 + 31468471 = 31468802
349 + 31468453 = 31468802
433 + 31468369 = 31468802
571 + 31468231 = 31468802
601 + 31468201 = 31468802
643 + 31468159 = 31468802

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.45.2.

Address: 1.224.45.2
Class: public
IPv4-mapped IPv6: ::ffff:1.224.45.2

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