Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491228, here are decompositions:

7 + 33491221 = 33491228
79 + 33491149 = 33491228
229 + 33490999 = 33491228
241 + 33490987 = 33491228
601 + 33490627 = 33491228
691 + 33490537 = 33491228
709 + 33490519 = 33491228
751 + 33490477 = 33491228

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.9.28.

Address: 1.255.9.28
Class: public
IPv4-mapped IPv6: ::ffff:1.255.9.28

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