Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147428082, here are decompositions:

13 + 2147428069 = 2147428082
61 + 2147428021 = 2147428082
109 + 2147427973 = 2147428082
181 + 2147427901 = 2147428082
199 + 2147427883 = 2147428082
223 + 2147427859 = 2147428082
379 + 2147427703 = 2147428082
439 + 2147427643 = 2147428082

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.38.242.

Address: 127.255.38.242
