Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147479178, here are decompositions:

7 + 2147479171 = 2147479178
181 + 2147478997 = 2147479178
211 + 2147478967 = 2147479178
241 + 2147478937 = 2147479178
457 + 2147478721 = 2147479178
577 + 2147478601 = 2147479178
661 + 2147478517 = 2147479178
829 + 2147478349 = 2147479178

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.238.138.

Address: 127.255.238.138
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.238.138
