Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147480768, here are decompositions:

61 + 2147480707 = 2147480768
127 + 2147480641 = 2147480768
157 + 2147480611 = 2147480768
241 + 2147480527 = 2147480768
331 + 2147480437 = 2147480768
457 + 2147480311 = 2147480768
541 + 2147480227 = 2147480768
571 + 2147480197 = 2147480768

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.244.192.

Address: 127.255.244.192
