Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489030, here are decompositions:

7 + 2147489023 = 2147489030
13 + 2147489017 = 2147489030
163 + 2147488867 = 2147489030
457 + 2147488573 = 2147489030
487 + 2147488543 = 2147489030
601 + 2147488429 = 2147489030
613 + 2147488417 = 2147489030
619 + 2147488411 = 2147489030

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.21.6.
