Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33559780, here are decompositions:

47 + 33559733 = 33559780
53 + 33559727 = 33559780
71 + 33559709 = 33559780
113 + 33559667 = 33559780
257 + 33559523 = 33559780
263 + 33559517 = 33559780
269 + 33559511 = 33559780
347 + 33559433 = 33559780

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.20.228.

Address: 2.0.20.228
Class: public
IPv4-mapped IPv6: ::ffff:2.0.20.228

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