Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473918, here are decompositions:

131 + 2147473787 = 2147473918
137 + 2147473781 = 2147473918
431 + 2147473487 = 2147473918
449 + 2147473469 = 2147473918
509 + 2147473409 = 2147473918
587 + 2147473331 = 2147473918
617 + 2147473301 = 2147473918
677 + 2147473241 = 2147473918

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.217.254.

Address: 127.255.217.254
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.217.254
