Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473808, here are decompositions:

229 + 2147473579 = 2147473808
241 + 2147473567 = 2147473808
331 + 2147473477 = 2147473808
379 + 2147473429 = 2147473808
439 + 2147473369 = 2147473808
457 + 2147473351 = 2147473808
541 + 2147473267 = 2147473808
577 + 2147473231 = 2147473808

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.217.144.

Address: 127.255.217.144
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.217.144
