Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489152, here are decompositions:

233 + 2147488919 = 2147489152
239 + 2147488913 = 2147489152
293 + 2147488859 = 2147489152
359 + 2147488793 = 2147489152
401 + 2147488751 = 2147489152
461 + 2147488691 = 2147489152
509 + 2147488643 = 2147489152
593 + 2147488559 = 2147489152

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.21.128.

Address: 128.0.21.128
Class: public
IPv4-mapped IPv6: ::ffff:128.0.21.128
