Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492540, here are decompositions:

7 + 2147492533 = 2147492540
13 + 2147492527 = 2147492540
19 + 2147492521 = 2147492540
211 + 2147492329 = 2147492540
223 + 2147492317 = 2147492540
241 + 2147492299 = 2147492540
379 + 2147492161 = 2147492540
643 + 2147491897 = 2147492540

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.34.188.

Address: 128.0.34.188
