Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561540, here are decompositions:

7 + 33561533 = 33561540
13 + 33561527 = 33561540
37 + 33561503 = 33561540
71 + 33561469 = 33561540
127 + 33561413 = 33561540
151 + 33561389 = 33561540
179 + 33561361 = 33561540
197 + 33561343 = 33561540

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.27.196.

Address: 2.0.27.196
Class: public
IPv4-mapped IPv6: ::ffff:2.0.27.196
