Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478288, here are decompositions:

29 + 2147478259 = 2147478288
139 + 2147478149 = 2147478288
199 + 2147478089 = 2147478288
239 + 2147478049 = 2147478288
271 + 2147478017 = 2147478288
409 + 2147477879 = 2147478288
479 + 2147477809 = 2147478288
587 + 2147477701 = 2147478288

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.235.16.

Address: 127.255.235.16
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.235.16
