Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475846, here are decompositions:

17 + 2147475829 = 2147475846
59 + 2147475787 = 2147475846
107 + 2147475739 = 2147475846
193 + 2147475653 = 2147475846
283 + 2147475563 = 2147475846
293 + 2147475553 = 2147475846
337 + 2147475509 = 2147475846
349 + 2147475497 = 2147475846

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.225.134.

Address: 127.255.225.134
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.225.134
