Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476978, here are decompositions:

41 + 2147476937 = 2147476978
47 + 2147476931 = 2147476978
107 + 2147476871 = 2147476978
137 + 2147476841 = 2147476978
239 + 2147476739 = 2147476978
359 + 2147476619 = 2147476978
461 + 2147476517 = 2147476978
809 + 2147476169 = 2147476978

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.229.242.

Address: 127.255.229.242
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.229.242

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