Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478976, here are decompositions:

17 + 2147478959 = 2147478976
113 + 2147478863 = 2147478976
257 + 2147478719 = 2147478976
317 + 2147478659 = 2147478976
479 + 2147478497 = 2147478976
677 + 2147478299 = 2147478976
683 + 2147478293 = 2147478976
827 + 2147478149 = 2147478976

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.237.192.

Address: 127.255.237.192
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.237.192
