Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147474480, here are decompositions:

3 + 2147474477 = 2147474480
97 + 2147474383 = 2147474480
241 + 2147474239 = 2147474480
331 + 2147474149 = 2147474480
367 + 2147474113 = 2147474480
409 + 2147474071 = 2147474480
631 + 2147473849 = 2147474480
643 + 2147473837 = 2147474480

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.220.48.

Address: 127.255.220.48
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.220.48
