Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509442, here are decompositions:

13 + 33509429 = 33509442
41 + 33509401 = 33509442
53 + 33509389 = 33509442
89 + 33509353 = 33509442
151 + 33509291 = 33509442
163 + 33509279 = 33509442
173 + 33509269 = 33509442
199 + 33509243 = 33509442

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.80.66.
