Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476804, here are decompositions:

41 + 2147476763 = 2147476804
197 + 2147476607 = 2147476804
593 + 2147476211 = 2147476804
677 + 2147476127 = 2147476804
773 + 2147476031 = 2147476804
827 + 2147475977 = 2147476804
953 + 2147475851 = 2147476804
1013 + 2147475791 = 2147476804

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.229.68.

Address: 127.255.229.68
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.229.68
