Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477642, here are decompositions:

43 + 33477599 = 33477642
83 + 33477559 = 33477642
89 + 33477553 = 33477642
151 + 33477491 = 33477642
179 + 33477463 = 33477642
229 + 33477413 = 33477642
251 + 33477391 = 33477642
311 + 33477331 = 33477642

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.212.10.

Address: 1.254.212.10
Class: public
IPv4-mapped IPv6: ::ffff:1.254.212.10

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