Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147561012, here are decompositions:

61 + 2147560951 = 2147561012
109 + 2147560903 = 2147561012
139 + 2147560873 = 2147561012
199 + 2147560813 = 2147561012
229 + 2147560783 = 2147561012
433 + 2147560579 = 2147561012
643 + 2147560369 = 2147561012
673 + 2147560339 = 2147561012

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.46.52.

Address: 128.1.46.52
Class: public
IPv4-mapped IPv6: ::ffff:128.1.46.52
