Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589626, here are decompositions:

59 + 31589567 = 31589626
113 + 31589513 = 31589626
293 + 31589333 = 31589626
443 + 31589183 = 31589626
557 + 31589069 = 31589626
569 + 31589057 = 31589626
599 + 31589027 = 31589626
647 + 31588979 = 31589626

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.4.250.

Address: 1.226.4.250
Class: public
IPv4-mapped IPv6: ::ffff:1.226.4.250

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