Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489282, here are decompositions:

19 + 2147489263 = 2147489282
79 + 2147489203 = 2147489282
139 + 2147489143 = 2147489282
193 + 2147489089 = 2147489282
199 + 2147489083 = 2147489282
223 + 2147489059 = 2147489282
541 + 2147488741 = 2147489282
709 + 2147488573 = 2147489282

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.22.2.
