Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557782, here are decompositions:

29 + 33557753 = 33557782
53 + 33557729 = 33557782
101 + 33557681 = 33557782
179 + 33557603 = 33557782
239 + 33557543 = 33557782
311 + 33557471 = 33557782
353 + 33557429 = 33557782
359 + 33557423 = 33557782

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.13.22.

Address: 2.0.13.22
Class: public
IPv4-mapped IPv6: ::ffff:2.0.13.22

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