Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147480948, here are decompositions:

7 + 2147480941 = 2147480948
157 + 2147480791 = 2147480948
241 + 2147480707 = 2147480948
271 + 2147480677 = 2147480948
307 + 2147480641 = 2147480948
337 + 2147480611 = 2147480948
397 + 2147480551 = 2147480948
421 + 2147480527 = 2147480948

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.245.116.

Address: 127.255.245.116
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.245.116
