Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476836, here are decompositions:

13 + 2147476823 = 2147476836
17 + 2147476819 = 2147476836
47 + 2147476789 = 2147476836
59 + 2147476777 = 2147476836
67 + 2147476769 = 2147476836
73 + 2147476763 = 2147476836
97 + 2147476739 = 2147476836
137 + 2147476699 = 2147476836

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.229.100.

Address: 127.255.229.100
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.229.100

Loopback (127.0.0.0/8) — refers to the local host. Not routable.

Unix timestamp
