Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489254, here are decompositions:

11 + 2147489243 = 2147489254
47 + 2147489207 = 2147489254
167 + 2147489087 = 2147489254
257 + 2147488997 = 2147489254
347 + 2147488907 = 2147489254
461 + 2147488793 = 2147489254
503 + 2147488751 = 2147489254
563 + 2147488691 = 2147489254

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.21.230.

Address: 128.0.21.230
