Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459400, here are decompositions:

13 + 31459387 = 31459400
43 + 31459357 = 31459400
61 + 31459339 = 31459400
79 + 31459321 = 31459400
109 + 31459291 = 31459400
139 + 31459261 = 31459400
199 + 31459201 = 31459400
277 + 31459123 = 31459400

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.8.72.

Address: 1.224.8.72
Class: public
IPv4-mapped IPv6: ::ffff:1.224.8.72

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