Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557440, here are decompositions:

11 + 33557429 = 33557440
17 + 33557423 = 33557440
23 + 33557417 = 33557440
29 + 33557411 = 33557440
41 + 33557399 = 33557440
53 + 33557387 = 33557440
83 + 33557357 = 33557440
101 + 33557339 = 33557440

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.11.192.

Address: 2.0.11.192
Class: public
