Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470724, here are decompositions:

3 + 31470721 = 31470724
23 + 31470701 = 31470724
71 + 31470653 = 31470724
83 + 31470641 = 31470724
101 + 31470623 = 31470724
167 + 31470557 = 31470724
281 + 31470443 = 31470724
401 + 31470323 = 31470724

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.52.132.

Address: 1.224.52.132
Class: public
IPv4-mapped IPv6: ::ffff:1.224.52.132

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

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, July 24, 3147 (YYYYMMDD (ISO basic)).
