Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623524, here are decompositions:

3 + 31623521 = 31623524
13 + 31623511 = 31623524
43 + 31623481 = 31623524
103 + 31623421 = 31623524
151 + 31623373 = 31623524
181 + 31623343 = 31623524
313 + 31623211 = 31623524
463 + 31623061 = 31623524

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.137.100.

Address: 1.226.137.100
Class: public
IPv4-mapped IPv6: ::ffff:1.226.137.100

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