Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566540, here are decompositions:

43 + 33566497 = 33566540
67 + 33566473 = 33566540
79 + 33566461 = 33566540
109 + 33566431 = 33566540
157 + 33566383 = 33566540
199 + 33566341 = 33566540
211 + 33566329 = 33566540
283 + 33566257 = 33566540

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.47.76.

Address: 2.0.47.76
Class: public
IPv4-mapped IPv6: ::ffff:2.0.47.76

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