Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557766, here are decompositions:

13 + 33557753 = 33557766
17 + 33557749 = 33557766
29 + 33557737 = 33557766
37 + 33557729 = 33557766
59 + 33557707 = 33557766
83 + 33557683 = 33557766
103 + 33557663 = 33557766
139 + 33557627 = 33557766

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.13.6.

Address: 2.0.13.6
Class: public
IPv4-mapped IPv6: ::ffff:2.0.13.6

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