Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500994, here are decompositions:

7 + 2147500987 = 2147500994
13 + 2147500981 = 2147500994
181 + 2147500813 = 2147500994
271 + 2147500723 = 2147500994
367 + 2147500627 = 2147500994
433 + 2147500561 = 2147500994
487 + 2147500507 = 2147500994
643 + 2147500351 = 2147500994

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.67.194.
