Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489556, here are decompositions:

13 + 2147489543 = 2147489556
19 + 2147489537 = 2147489556
53 + 2147489503 = 2147489556
73 + 2147489483 = 2147489556
83 + 2147489473 = 2147489556
257 + 2147489299 = 2147489556
293 + 2147489263 = 2147489556
313 + 2147489243 = 2147489556

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.23.20.

Address: 128.0.23.20
