Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475412, here are decompositions:

11 + 2147475401 = 2147475412
179 + 2147475233 = 2147475412
191 + 2147475221 = 2147475412
233 + 2147475179 = 2147475412
263 + 2147475149 = 2147475412
449 + 2147474963 = 2147475412
461 + 2147474951 = 2147475412
491 + 2147474921 = 2147475412

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.223.212.

Address: 127.255.223.212
