Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488440, here are decompositions:

59 + 33488381 = 33488440
71 + 33488369 = 33488440
107 + 33488333 = 33488440
131 + 33488309 = 33488440
137 + 33488303 = 33488440
239 + 33488201 = 33488440
317 + 33488123 = 33488440
353 + 33488087 = 33488440

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.254.56.

Address: 1.254.254.56
Class: public
IPv4-mapped IPv6: ::ffff:1.254.254.56

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