Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475398, here are decompositions:

31 + 2147475367 = 2147475398
67 + 2147475331 = 2147475398
337 + 2147475061 = 2147475398
547 + 2147474851 = 2147475398
907 + 2147474491 = 2147475398
919 + 2147474479 = 2147475398
1039 + 2147474359 = 2147475398
1249 + 2147474149 = 2147475398

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.223.198.

Address: 127.255.223.198
