Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33544520, here are decompositions:

3 + 33544517 = 33544520
7 + 33544513 = 33544520
19 + 33544501 = 33544520
43 + 33544477 = 33544520
151 + 33544369 = 33544520
199 + 33544321 = 33544520
313 + 33544207 = 33544520
379 + 33544141 = 33544520

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.217.72.

Address: 1.255.217.72
Class: public
IPv4-mapped IPv6: ::ffff:1.255.217.72

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