Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147480692, here are decompositions:

41 + 2147480651 = 2147480692
101 + 2147480591 = 2147480692
173 + 2147480519 = 2147480692
233 + 2147480459 = 2147480692
263 + 2147480429 = 2147480692
653 + 2147480039 = 2147480692
683 + 2147480009 = 2147480692
701 + 2147479991 = 2147480692

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.244.116.

Address: 127.255.244.116
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.244.116
