Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477460, here are decompositions:

17 + 2147477443 = 2147477460
41 + 2147477419 = 2147477460
61 + 2147477399 = 2147477460
67 + 2147477393 = 2147477460
137 + 2147477323 = 2147477460
211 + 2147477249 = 2147477460
223 + 2147477237 = 2147477460
251 + 2147477209 = 2147477460

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.231.212.

Address: 127.255.231.212
