Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147479988, here are decompositions:

97 + 2147479891 = 2147479988
109 + 2147479879 = 2147479988
307 + 2147479681 = 2147479988
331 + 2147479657 = 2147479988
439 + 2147479549 = 2147479988
457 + 2147479531 = 2147479988
499 + 2147479489 = 2147479988
541 + 2147479447 = 2147479988

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.241.180.

Address: 127.255.241.180
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.241.180
