Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476640, here are decompositions:

97 + 2147476543 = 2147476640
223 + 2147476417 = 2147476640
241 + 2147476399 = 2147476640
313 + 2147476327 = 2147476640
349 + 2147476291 = 2147476640
457 + 2147476183 = 2147476640
499 + 2147476141 = 2147476640
643 + 2147475997 = 2147476640

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.228.160.

Address: 127.255.228.160
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.228.160
