Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489342, here are decompositions:

43 + 2147489299 = 2147489342
79 + 2147489263 = 2147489342
139 + 2147489203 = 2147489342
199 + 2147489143 = 2147489342
283 + 2147489059 = 2147489342
601 + 2147488741 = 2147489342
769 + 2147488573 = 2147489342
1009 + 2147488333 = 2147489342

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.22.62.

Address: 128.0.22.62
