Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473478, here are decompositions:

109 + 2147473369 = 2147473478
127 + 2147473351 = 2147473478
181 + 2147473297 = 2147473478
211 + 2147473267 = 2147473478
691 + 2147472787 = 2147473478
727 + 2147472751 = 2147473478
877 + 2147472601 = 2147473478
1009 + 2147472469 = 2147473478

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.216.70.

Address: 127.255.216.70
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.216.70
