Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561998, here are decompositions:

79 + 33561919 = 33561998
181 + 33561817 = 33561998
199 + 33561799 = 33561998
229 + 33561769 = 33561998
439 + 33561559 = 33561998
619 + 33561379 = 33561998
727 + 33561271 = 33561998
829 + 33561169 = 33561998

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.29.142.

Address: 2.0.29.142
Class: public
IPv4-mapped IPv6: ::ffff:2.0.29.142

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