Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475188, here are decompositions:

7 + 2147475181 = 2147475188
127 + 2147475061 = 2147475188
241 + 2147474947 = 2147475188
307 + 2147474881 = 2147475188
337 + 2147474851 = 2147475188
379 + 2147474809 = 2147475188
709 + 2147474479 = 2147475188
829 + 2147474359 = 2147475188

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.222.244.

Address: 127.255.222.244
