Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561642, here are decompositions:

31 + 33561611 = 33561642
43 + 33561599 = 33561642
71 + 33561571 = 33561642
83 + 33561559 = 33561642
109 + 33561533 = 33561642
139 + 33561503 = 33561642
173 + 33561469 = 33561642
229 + 33561413 = 33561642

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.28.42.

Address: 2.0.28.42
Class: public
IPv4-mapped IPv6: ::ffff:2.0.28.42

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