Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472704, here are decompositions:

5 + 31472699 = 31472704
41 + 31472663 = 31472704
71 + 31472633 = 31472704
113 + 31472591 = 31472704
167 + 31472537 = 31472704
353 + 31472351 = 31472704
443 + 31472261 = 31472704
503 + 31472201 = 31472704

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.60.64.

Address: 1.224.60.64
Class: public
IPv4-mapped IPv6: ::ffff:1.224.60.64

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