Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467188, here are decompositions:

19 + 2147467169 = 2147467188
67 + 2147467121 = 2147467188
131 + 2147467057 = 2147467188
179 + 2147467009 = 2147467188
197 + 2147466991 = 2147467188
241 + 2147466947 = 2147467188
257 + 2147466931 = 2147467188
401 + 2147466787 = 2147467188

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.191.180.

Address: 127.255.191.180
