Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443022, here are decompositions:

19 + 2147443003 = 2147443022
61 + 2147442961 = 2147443022
199 + 2147442823 = 2147443022
211 + 2147442811 = 2147443022
271 + 2147442751 = 2147443022
349 + 2147442673 = 2147443022
409 + 2147442613 = 2147443022
463 + 2147442559 = 2147443022

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.97.78.

Address: 127.255.97.78
