Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476928, here are decompositions:

31 + 2147476897 = 2147476928
109 + 2147476819 = 2147476928
139 + 2147476789 = 2147476928
151 + 2147476777 = 2147476928
229 + 2147476699 = 2147476928
241 + 2147476687 = 2147476928
409 + 2147476519 = 2147476928
547 + 2147476381 = 2147476928

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.229.192.

Address: 127.255.229.192
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.229.192
