Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477930, here are decompositions:

47 + 33477883 = 33477930
113 + 33477817 = 33477930
137 + 33477793 = 33477930
251 + 33477679 = 33477930
271 + 33477659 = 33477930
281 + 33477649 = 33477930
331 + 33477599 = 33477930
439 + 33477491 = 33477930

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.213.42.

Address: 1.254.213.42
Class: public
IPv4-mapped IPv6: ::ffff:1.254.213.42

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