Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525442, here are decompositions:

3 + 33525439 = 33525442
101 + 33525341 = 33525442
131 + 33525311 = 33525442
233 + 33525209 = 33525442
383 + 33525059 = 33525442
443 + 33524999 = 33525442
479 + 33524963 = 33525442
491 + 33524951 = 33525442

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.142.194.

Address: 1.255.142.194
Class: public
IPv4-mapped IPv6: ::ffff:1.255.142.194

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