Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572100, here are decompositions:

17 + 33572083 = 33572100
19 + 33572081 = 33572100
59 + 33572041 = 33572100
71 + 33572029 = 33572100
73 + 33572027 = 33572100
103 + 33571997 = 33572100
137 + 33571963 = 33572100
157 + 33571943 = 33572100

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.69.4.

Address: 2.0.69.4
Class: public
IPv4-mapped IPv6: ::ffff:2.0.69.4

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