Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475958, here are decompositions:

29 + 2147475929 = 2147475958
59 + 2147475899 = 2147475958
107 + 2147475851 = 2147475958
167 + 2147475791 = 2147475958
317 + 2147475641 = 2147475958
449 + 2147475509 = 2147475958
461 + 2147475497 = 2147475958
557 + 2147475401 = 2147475958

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.225.246.

Address: 127.255.225.246
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.225.246
