Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459332, here are decompositions:

11 + 31459321 = 31459332
41 + 31459291 = 31459332
43 + 31459289 = 31459332
71 + 31459261 = 31459332
109 + 31459223 = 31459332
131 + 31459201 = 31459332
181 + 31459151 = 31459332
199 + 31459133 = 31459332

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.8.4.

Address: 1.224.8.4
Class: public
IPv4-mapped IPv6: ::ffff:1.224.8.4

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